Most of the time (i.e. for a couple of days now) the program has been

 Traceback (most recent call last):

But msghdr["subject"] is surely just a string isn't it?


Obviously not.


 Why is it
complaining about something of type 'Header'?


Because you tried to iterate it.  Header is defined in email.header 
(find 'class Header').  It has a __str__ to turn one into a string.  I 
have never read the email doc so I have no idea if 'subject' being a 
Header is a bug.


Grepping email package for case-sensitive word 'Header' also returns 3 
comment saying that something might be a Header, so stringify it.  I 
have the impression that these might have been added after the original 
code, perhaps in response to error reports.  In any case, you can do the 
same.



As I said the program has been running happily for a couple of days
with no errors, I guess it must be something strange in a mail that
has broken things - but what?


To determine that, look at (after logging or saving) the raw email and 
maybe the resulting Message (using msg.as_string).



# Read the message from standard input and make a message object from it
#
msg = mailbox.MaildirMessage(sys.stdin.buffer.read())


raw = sys.stdin.buffer.read()  # So can save
msg = mailbox.MaildirMessage(raw)


msghdr["subject"] = msg.get("Subject", "unknown")

...

 if sbstrip in msghdr["subject"]:


Replace with

  sub = msghdr["subject"]
  if 'Header' in str(sub.__class__):
# Or import email.message.class and use isinstance
   # stringify or skip or ???
   else:

 msg.replace_header("Subject", msghdr["subject"].replace(sbstrip,

At some point, the internal code for the "in" operator is likely
iterating over the elements of msghdr["subject"].

That error message doesn't make a lot of sense if msghdr["subject"] is a
sub-class of str.  It makes more sense if msghdr["subject"] is something
else.

IMO, you need more information in the log, a try/except block to prevent
the code from crashing, and, yes, perhaps some patience to wait for it
to happen again.

Sometimes, developing software isn't all fortune, fame, and glory.  ;-)

An intermittent problem!  They're our favorite!  ;-)

Seriously, though, do you have a message that provokes the problem?  Is
there a log at all?  Can you re-run that message through the code, in a
debugger or otherwise?

Yes, I did consider the str() approach but it feels a bit like making
the problem go away without actually fixing it.

However since the code in question is only 'cosmetic' (removing
unwanted [list name] from the subject, it's not all *that* important
to handle it properly.  I just need to stop the error from killing my
program.

That's a point, with the clues you have given me I can try some 'bad'
subject text and see if I can reproduce the error.

Thanks again.

I have output everything that appears, I've not changed it at all.
It's the whole content of the file ~/tmp/mail.err as it's the only
error that has occurred for the last day or so.  The error log is
created by the line:-

sys.stderr = open("/home/chris/tmp/mail.err", 'a')

So that's everything that was output to stderr.

I think you are puzzled in the same way that I was, the error message
doesn't make a lot of sense.

Re: I need some help interpreting this error

[Stestagg]

I don't particularly like to encourage this shotgun help request because,
as previous commenter suggests, debugging this yourself is best.

Sometimes debugging is super hard, and especially so when uncommon
situations occur, but it's always far easier to debug things when you have
visibility into the system under test.

However, in this case, the email code is super complex, and this scenario
also looks very uncommon, but not unique: (
https://github.com/Sydius/mbox-to-txt/issues/2), so you successfully
nerd-sniped me :).

My *guess*, from reading the python standard library source code is that
you came across an email with some content in the subject line that is
considered a "surrogate", roughly, some badly encoded unicode or binary
data in it.

When this happens, the code in some situations (depending on the policy...)
may return a header.Header() instance, rather than a
headerregistry.UniqueUnstructuredHeader
(which would have had a headerregistry.BaseHeader (mro: str) dynamically
attached).

header.Header() does not inherit from str, and thus would throw the
traceback you observed.

Your suggestion of a try: catch: may make sense, alternately, you could
wrap the result in a call to str():

if sbstrip in str(msghdr["subject"]):

which should attempt to encode the binary into some form of string object
for comparison (I haven't checked exactly what would happen, beyond: it
tries).

It should be possible to create a test mbox with some funky bytes in the
subject, and try to reproduce it that way.

That's exactly what puzzled me! The line that gets the value is:-

msghdr["subject"] = msg.get("Subject", "unknown")

What I need to know is how that can return a value of type Header, and
not a str.

I think the only sane approach at the moment may be to add a try:
except: and output some diagnostic information.  Though there may
still be an issue when trying to output the "what is it" object to the
error log of course.

I don't know, what would I do?  :-)

Without knowing what provokes the problem I could be waiting for days
or weeks even before I see the error again.  As I'd need to print the
type for every message I'd get some big logs or I'd need to add a try:
except to trap the specific error.

So we still don't know what the content of msghdr["subject"] is at the
time the error occurs.  I don't mean to sound harsh, but that the
documentation and the code are correct, and that they match, remain
assumptions.  Sometimes, seeing an actual value tells you what went
wrong (e.g., "oh, that's the sender's address, not the receiver's
address," "oh, that's my 'time' class, not the one from the standard
library").

The traceback tells you that msghdr["subject"] is of type Header.  Is
Header a sub-class of str?

Again, the worst case of looking at the value (whether in a log or in a
debugger) is that you verify your assumption.

That's good news about subject-less emails not generating an error, and
separate (possibly related) good news about your code handling an email
without a subject header.  ;-)

The documentation says "Headers are represented by customized
subclasses of str", so it's a sub-class of str.

If you look at the code (and the documentation) if there's no subject
header I'll get the string "unknown", I've also tried sending myself
an E-Mail with no header and not provoked the error.

Isn't it?  ;-)

First step:  Print msghdr["subject"] and its type to know for sure.  The
worst case is that you'll verify your assumption.

IIRC, the subject header is actually optional.  Maybe someone sent a
message without a subject?  Is msghdr["subject"] None?

I need some help interpreting this error

[Chris Green]

I'm running this using Python 3.7 on a Linux system.

Most of the time (i.e. for a couple of days now) the program has been
satifactorily delivering mail messages, hundreds of them.  However one
mail message has provoked the following error:-

chris@cheddar$ tail mail.err
Traceback (most recent call last):
  File "/home/chris/.mutt/bin/filter.py", line 95, in 
if sbstrip in msghdr["subject"]:
TypeError: argument of type 'Header' is not iterable


But msghdr["subject"] is surely just a string isn't it?  Why is it 
complaining about something of type 'Header'?

As I said the program has been running happily for a couple of days 
with no errors, I guess it must be something strange in a mail that
has broken things - but what?

Hi Justin,

the default markup is currently set to restructuredtext:

https://github.com/python/pythondotorg/blob/master/jobs/models.py

but this can be changed to any of these supported ones:

https://github.com/jamesturk/django-markupfield

as long as we make sure that all existing records continue
to be set to ReST (to not mess up the formatting).

Since I had a look at WYSIWYG editors, some new ones may have
surfaced.

The templates are defined here:

https://github.com/python/pythondotorg/tree/master/templates/jobs

and the main project page has instructions on how to get
a local copy of the website working:

I might be able to help implement a wysiwyg editor. The only issue I can
think of at the moment
would be finding a way to determine if the template should render wysiswyg

Need some help with Python Job Board

[Skip Montanaro]

The Python Job Board could use a little help in a couple areas. One, we can
always use help reviewing and approving (or rejecting) submissions. The
backlog keeps growing, and the existing volunteers who help can't always
keep up. (This is a good problem to have, reflecting on Python's broad
popularity in many application domains.)

Two, and perhaps more important, the submission form really needs to
support WYSIWYG editing. Apparently, most posters are unable to handle
markup-based systems, probably just pasting content from Word documents.
Making this change would streamline the review process, as formatting
problems are currently the biggest impediment to successful submissions.
There is an open ticket to add this feature:

https://github.com/python/pythondotorg/issues/655

If you can help with either task, please drop a note to j...@python.org.

Argument groups are a feature to control the help output from the
parser:

 When an argument is added to the group, the parser treats it just
 like a normal argument, but displays the argument in a separate
 group for help messages.

You don't want to use the “argument groups” feature for that, because
that's not what it does.

I don't know of a way to have the argument parser know the separation
you're talking about, without using a subparser.

You will need to maintain that separation yourself, outside the parser.

One simple way (I have not tried this)::

argument_names_by_group = {
'foo': {'lorem', 'donec', 'fusce'},
'bar': {'aliquam', 'nunc'},
}

args = parser.parse_args()

args_by_group = {
group_name: {
getattr(arg_name)
for arg_name in argument_names_by_group[group_name]
}
for group_name in argument_names_by_group
}

Need some help with argparse

[Kryptxy via Python-list]

Hi,
I am trying to figure out something with argparse.
Here is a scenario:

I have a group of arguments, say: (-a, -b, -c, -d, -e) [lets call it group1]
I have another group, say: (-z, -y, -x, -w) [lets call it group2]

Code:
import argparse
parser = argparse.ArgumentParser(description="Test this shiz")
group1= parser.add_argument_group("Group 1")
group2= parser.add_argument_group("Group 2")

group1.add_argument('-a', '--extendA', action="store_true", help="HELP")
group1.add_argument('-b', '--extendB', action="store_true", help="HELP")
group1.add_argument('-c', '--extendC', action="store_true", help="HELP")
group1.add_argument('-d', '--extendD', action="store_true", help="HELP")
group1.add_argument('-e', '--extendE', action="store_true", help="HELP")

# Similarly for group 2:
group2.add_argument('-z', '--extendZ', action="store_true", help="HELP")
group2.add_argument('-y', '--extendY', action="store_true", help="HELP")
group2.add_argument('-x', '--extendX', action="store_true", help="HELP")
group2.add_argument('-w', '--extendW', action="store_true", help="HELP")

args = parser.parse_args()

Now I want to get arguments of group1 and group2 separately.
If I print(args) - I get arguments from both the groups.
Also group1.parse_args() does not work (since ArgumentGroup does not have 
parse_args() method)

How can I get all arguments of group 1 ONLY? Same goes for group 2?
I tried subparsers too - but they require a mandatory `positional argument` - 
which is not application's requirement.

Any kind of help is appreciated.
Thank you!

Manageing larger projects is in general helped by some kind of modularization:
you split the whole implementation into different parts which have
high internal and low external interaction. While the total
complexity increases, you have often a chance to concentrate
on a part only and this part is far less complex the the whole.


OOP is just one kind of modularization. Not all problems can
make high use of OOP modularization.


For OOP friendly problems, you can easily identify objects. They have
state and functions operating on this state (those functions are called
"method"s). The state is mostly relevant only for the object internally
and less (if at all) for the external world.


In your case, the search service itself might be an object. And the queries
might be objects. To gain something, you must have interesting
operations on those objects - operations that manipulate a mostly irrelevant
(but fairly complex) internal state.

> Also, can someone point me to some (small) project where something similar is 
> being implemented?

You might have a look at "Products.AdvancedQuery" (--> "PyPI").
Download its source; you will find a documentation in the
folder "Products/AdvancedQuery/doc/". It models
queries as objects and the relevant operations are query constructors.

You (likely) will not be able to "run" it. It depends on
a search service called "ZCatalog" (part of the web application framework
"Zope"). This search service, too, is implemented by an object.
To use it, you would need "Zope". But you can download the source
(--> "PyPI"; its name is "Products.ZCatalog") and look
at the interface description in "Products.ZCatalog.interfaces.py"
to learn about the "ZCatalog" methods. This file also contains
a good documentation (via so called "docstring"s).


Interfaces are a general way to document the relevant parts
of objects/classes for "external use". They are heavily used by "Zope".

Need some help managing project and making it a little simple (pretty messed up code)

[Kryptxy via Python-list]

Hello,
I am new to python. While learning python, I began a side project. Its a 
command-line search program.

Here: https://github.com/kryptxy/torrench

The project is becoming a little difficult to manage, and before it becomes 
more complex, I'd like to sort it out a little and make it more managable and 
readable.
As of now, I haven't used any OOP concepts (no classes) bc while I was 
learning, I didn't reach the OOP part, and then spent too much time on the 
project (and that's probably the part I want help with). Now however, I do know 
about classes and basics about OOP.

But, I am unable to understand how I should begin structuring the project 
(updating code according to OOP). If someone could have a look? Could really 
use some suggestions/ideas.

Also, can someone point me to some (small) project where something similar is 
being implemented? (as in sharing similar project-structure). They can be 
really helpful. I did have a look at youtube-dl source. Not helpful. Seemed too 
complex.

Hope for some positive response.

Thank you.

Find the correct name for the key by printing out `weather_obj`.  At least I 
think so, as the line above does not match the line that you've given.

Use a valid key for weather_obj.  Check doc or add

before the failing subscription.

Oops, is that your personal token? You are probably not supposed to publish

You have to replace nb with one of the allowed values listed on the site.

Again, you have to pick one of the values listed -- unless you want Norsk

We're unpaid volunteers, we're not being paid to debug your code. Don't dump
over 300 lines of code in our lap and expect us to debug it. If you can't
spend the time simplifying the problem and removing all the irrelevant
details, how can you expect us to do it for you?

If you want help, make it easy for people to help you. Cut your code down to
the simplest, shortest amount of code that demonstrates the problem. If
your code has nothing to do with the GUI, cut out all the GUI code.

Hello kcollins15,

   Just try this.

import win32api
import win32net

###

Code to create user goes here

###

##

# Code to add created user to a group (on a local machine)

serverName =  + win32api.GetComputerName()
domain = win32api.GetDomainName()
data = [{domainandname : domain + \\TestUser}]
print Adding
win32net.NetLocalGroupAddMembers(serverName,Users,3,data)
print Added Successfully !!

##

This is working piece of code. It worked for me, I needed to add newly
created user to the group called Users.

Just replace Users with Administrator. 

I'll get back soon on how and when NetGroupAddUser() should be used.

Hope it helps...!

Kryptox, you have chosen the correct algorithm to calculate a MAC. Very

But the designers of the game are using an improper algorithm.
Apparently they don't know much about cryptography, especially length

Need some help confirming transactions using sha256

[kryptox . exchange]

I'm wondering if anyone can help me as I can't seem to get this to work. There 
is an online dice game that is provably fair by calculating the 'dice roll' 
using using a sha256 hash calculated against my transaction ID generated by me. 
The secret used to make the calculation is revealed at the end of each day thus 
allowing you to prove they didn't cheat. So they provide the following to allow 
you to verify the calculation of the dice roll:

Secret used =

Lucky Number 0x48e4 = 18660


So, I'm doing the following:

idx 1 should equal 18660 but it doesn't. What am I doing wrong?


Secondly, I'm wondering if someone could help take it one step further. I would 
like to import a .txt file with a unique transaction ID on each line. So txid = 
transactions.txt or something like this. I would like it to get the lucky 
number based on a static sha256 which I would supply and the script would 
output the result to a text file. I'd like the output to be for idx 1 only.

ie.
txid here, lucky number for idx 1

need some help with unexpected signal exception when using input from a thread (Pypy 1.9.0 on osx/linux)

[Irmen de Jong]

Hi.
Using Pypy 1.9.0. Importing readline. Using a background thread to get input() 
from
stdin. It then crashes with:

  File /usr/local/Cellar/pypy/1.9/lib_pypy/pyrepl/unix_console.py, line 400, 
in restore
signal.signal(signal.SIGWINCH, self.old_sigwinch)
ValueError: signal() must be called from the main thread

Anyone seen this before? What's going on?
When I don't import readline, or do the input() from within the main thread, 
the problem
disappears.

(I tried to reproduce it in a small test scenario but unfortunately have not 
been able
to do so yet. Haven't figured out yet what the additional factors are that 
trigger this
problem. A simple import readline and input() from a new thread doesn't seem to 
trigger
it, unfortunately)

Apparently, input is not apt to be called from a background thread.

I have no idea why signal should only be callable from the main thread.
I do not think this makes much sense. Speak with the Pypy developers
about this.

You need to download and install the Windows-specific extensions:

Have you installed the Win32 extensions?

From http://www.devx.com/opensource/Article/37233/0/page/3

Author's Note: the win32clipboard module is not part of the standard 
Python distribution on Windows. You can get it (along with lots of other 
comprehensive Python bindings to Win32 APIs) as part of the Win32 
extensions project on SourceForge. Alternatively, the module is also 
bundled with the ActivePython distribution for Windows.

Why bother using codepad for this?  The problem occurs parsing the 3rd 
line, so you only needed that and the traceback.


Have you installed the Win32 extensions?  If you think you have, can you 
find the file ?


C:\ProgFiles\Python26\Lib\site-packages\win32\win32clipboard.pyd

Naturally, your install directory may be different.  But it should be in 
the site-packages directory, which is where add-ons are installed.

It seems you are iterating over *all* accumulated templates so far, over

Looks like the source of quadratic runtime for me.

 Hi all,

 I'm trying to write a loop that will build a list of template

 My current implementation is *really slow*.  It took 15 minutes to

 #combinations = 12 small template strings ie {{ city }},
 {{ state }}...
 #states = either a django model or a list of 50 states
 #cities = either a django model of 400 cities or a smaller list of
 cities.

 templates = []
 for c in combinations:

             if type(geo) is City:
                 cities = state.city_set.all()

             templates = [k.replace('{{ state }}',
 state.state).replace('{{ state_abbr }}', state.abbreviation) for k in

The line above does a lot of unnecessary work as you iterate over lots
of templates which have already been completely substituted.

     elif len(geo):
         for city in geo:
             templates.append(c.template.replace('{{ city }}', city))
     else:
         #no cities or states so add roots
         templates.append(c.template)

 The final output needs to be a list of the templates combined with all
 the states and cities (some templates will only have the city, some
 only the state).

 Any ideas how I can optimize this?

 Thanks!

I would suggest this (untested):

HTH

Even better would be to iterate over states, then cities, then only
templates.

Need some help speeding up this loop

[erikcw]

Hi all,

I'm trying to write a loop that will build a list of template
strings.

My current implementation is *really slow*.  It took 15 minutes to
finish. (final len(list) was about 16k entries.)

#combinations = 12 small template strings ie {{ city }},
{{ state }}...
#states = either a django model or a list of 50 states
#cities = either a django model of 400 cities or a smaller list of
cities.

templates = []
for c in combinations:
if len(states):
for state in states:
if type(geo) is City:
cities = state.city_set.all()
else:
cities = geo
for city in cities:
if type(city) is City:
city = city.city
templates.append(c.template.replace('{{ city }}',
city))
templates.append(c.template) #just in case there are no
cities
templates = [k.replace('{{ state }}',
state.state).replace('{{ state_abbr }}', state.abbreviation) for k in
templates]
elif len(geo):
for city in geo:
templates.append(c.template.replace('{{ city }}', city))
else:
#no cities or states so add roots
templates.append(c.template)

The final output needs to be a list of the templates combined with all
the states and cities (some templates will only have the city, some
only the state).

Any ideas how I can optimize this?

Thanks!

Re: need some help in serving static files inside a wsgi apps

[Martin v. Löwis]

 I guess, Apache does some kind of memory caching for files, which are often
 requested and small enough to fit into the system memory. 

Are you sure about this? I could not find anything in the documentation
(other than mod_cache and friends, which is an unrelated functionality).
Also, I don't see the need for Apache to cache frequently requested
files itself. Instead, the operating system will cache frequently
requested directories and files in memory, and it will do the same for
a Python web server.

Martin

No, I'm not.  That's why I said I guess ;)

Of course, a modern OS kernel will perform caching anyway, but this is most
likely slower than in-process caching, since it will still require context
switches from userspace into kernel space.

Considering this, it seems reasonable to me, that apache does memory
caching, but I'm by far not sure, I wouldn't put a bet on this ;)

I'm not aware of that, and I even more seriously doubt it. Because 
caching is a complicated, domain-dependend subject that would 
*immediately* cry for configuration - e.g. caching strategies and such.


And a common idiom for apache  caching is to use Squid as reverse 
proxy. Which wouldn't be the case would apache cache by itself.

This is available in current apache with mod_file_cache (for an

As I said - explicit configuration is needed. And of course apache  
it's module system are flexible enough to allow caching as add-on. But 
Sebastian speculated about some behind the scenes automatic caching. 
Which apparently isn't there.

Interestingly enough, this *doesn't* do memory caching for files.
Instead, it either keeps the file handle open, so you can seek to the
beginning of the file on the next request (avoiding the directory
lookup), or you can mmap the file. However, even if you mmap the file,
it is still the operating system's choice whether or not to cache the
file contents in memory.

need some help in serving static files inside a wsgi apps

[Tool69]

Hi,

Until now, I was running my own static site with Python, but I'm in
need of dynamism.

After reading some cgi tutorials, I saw Joe Gregorio's old article
Why so many Python web frameworks? about wsgi apps [http://
bitworking.org/news/Why_so_many_Python_web_frameworks] and have a
question about it. The code he gave works like a charm (I had to make
a little change because SQLAlchemy has changed since), but how the
hell can I serve static files (css, js, images, etc.) within an wsgi
app, ie inside a '/static' directory ?!

Sorry if my question is a stupid one, but I cannot find an easy way to
do this. Each tutorial I'm reading out there does not talk about them
at all. All of my python books didn't mention wsgi either.

I know I could use web.py, web2py, Cherrypy, Django, Pylons, etc. but
I'm trying to understand basics of web dev. from their roots.

thanks in advance for any advice ,

Kib.

Hi Diez,

and thanks for yout help. In fact I already found it but never managed 
to get it work because the static doc says :


from wsgiref.simple_server import make_server
import static
make_server('localhost', , static.Cling('/var/www')).serve_forever()

and inside J.Gregorio's tutorial it is:

from wsgiref.simple_server import WSGIServer, WSGIRequestHandler
httpd = WSGIServer(('localhost', 8080), WSGIRequestHandler)
httpd.set_app(urls.urls)

It does not use 'make_server()' so how can I adapt it ?

I finally managed to work with static files with a little hack, but it's 
ugly because I'm reading each static file per request.

static.Cling is a wsgi-app. The other code just makes a specific

Need some help with 'with'

[Mike Kent]

I recently found myself needing to do this a lot:

lock a record in a file
read the record into a buffer
alter the buffer
write the buffer back to the record
unlock the record

I'd love to be able to create a context for this to use with the
'with' statement, something like:

from __future__ import with_statement
from contextlib import contextmanager
from fcntl import lockf, LOCK_EX, LOCK_UN

@contextmanager
def lockedRecord(fileObj, offset, length):
lockf(fileObj, LOCK_EX, offset, length)
try:
fileObj.seek(offset)
buff = fileObj.read(length)
newBuff = (yield buff)
fileObj.seek(offset)
fileObj.write(newBuff)
finally:
lockf(fileObj, LOCK_UN, offset, length)

Which would let me write code like:

fileObj = open(myfile.dat, r+b)

with lockedRecord(fileObj, 20, 10) as rec:
newRec = rec.replace('foo', 'bar')
# Somehow send newRec back into the context

I know you can now send data back into a generator via the send method
of the generator, however i don't seem to have access to the generator
object itself.

I figure that if instead of returning the buffer from the context
directly, I instead returned the buffer in a list, I could then change
the buffer, put it in the returned list, then I'd have access to it
back inside the context, but this seems a bit ugly.

Does anyone have insight into the right way of doing this?

 I want to create a program that I type in a word.

You can see that Python has a command to input strings from the
command line.

 chaos
 each letter equals a number
 A=1
 B=20
  and so on.
 So Chaos would be
 C=13 H=4 A=1 O=7 S=5
 I want to then have those numbers
 13+4+1+7+5 added together to be 30.
 How can I do that?

Python has a dictionary data structure called dict(), or {}, that you
can use to map your letters to those numbers. With it you can created
the letter-number association.

Then you can scan the characters of the input string one after the
other, and sum their values into a single total value. Try writing
that code, and then show it to us, we can give more suggestions if you
need them...

as an alternative for the suggest dictionary approach you could study 
the built in functions ord() and chr(), see the documentation 
(http://docs.python.org/lib/built-in-funcs.html)

 Also, just curious, but, how could I then have the 3 and 0 added

 Please help me out.

No, since the definition of a never called function won't help.

Try the following standard strategy: Make a copy of your project and
reduce it (removing functionality) until the error doesn't appear
anymore. If it does *not* vanish, post your short code here or in

I'm looking for what is probably an simple solution I can't figure out
on my own.  I'm writing an SSH server based on the example on the web
(using conch).  I'm trying to figure out how to detect when the client
exists (for example, when I just close out PuTTY), but I can't get this
to work right.  Looking through the API docs I found connectionLost(),
which I put in my protocol class (EchoProtocol in the example), but it's

of impending conceptual intractability where the quest for the magic 
formula becomes particularly fascinating. I also suspect that some 
problems are impossible to solve with a single expression and that no 
test of intractability exists other than giving up after so many hours 
of trying.
With reference to the OP's question, what speaks against passing his 
texts through several simple expressions in succession? Speed of 
execution? Hardly. The speed penalty would not be perceptible. 
Conversely, in favor of multiple expressions speaks that they can be 
kept simple and that the performance of the entire set can be 
incrementally improved by adding another simple expression whenever an 
unexpected contingency occurs, as they may occur at any time with 
informal systems. One may not win a coding contest this way, but saving 
time isn't bad either, or is even better.

hear! hear!

for dense guys like myself, regular expressions work best if you use 
them as simple tokenizers, and they suck pretty badly if you're trying 
to use them as parsers.

and using a few RE:s per problem (or none at all) is a perfectly good 
way to get things done.

Yes, it seems to me that REs are a bit hit and miss - the only way to
tell if you've got a RE right is by testing exhaustively - but you
can never be sure They are fine for simple pattern matching though.

There are advantages to the regex method. It is faster than sending an
email and getting a positive or negative return code. The delay may not
be acceptable in many applications. Secondly, the false negatives found
by a reasonable regex will be few compared to the number you'd get if
the smtp server went down, or a remote relay was having problems
delivering the message etc etc.

From a business point of view, it is probably more important to reduce
the number of false negatives than to reduce the number of false
positives - every false negative is a potential loss of a customer.
False positives? Who cares really as long as they are paying ;-)

[codefire]

Hi,

I am trying to get a regexp to validate email addresses but can't get
it quite right. The problem is I can't quite find the regexp to deal
with ignoring the case [EMAIL PROTECTED], which is not valid. Here's
my attempt, neither of my regexps work quite how I want:

[code]
import os
import re

s = 'Hi [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] @@not
[EMAIL PROTECTED] partridge in a pear tree'
r = re.compile(r'[EMAIL PROTECTED]@\s]+\.\w+')
#r = re.compile(r'[EMAIL PROTECTED]')

addys = set()
for a in r.findall(s):
addys.add(a)

for a in sorted(addys):
print a
[/code]

This gives:
[EMAIL PROTECTED]
[EMAIL PROTECTED]
[EMAIL PROTECTED]   -- shouldn't be here :(
[EMAIL PROTECTED]

Nearly there but no cigar :)

I can't see the wood for the trees now :) Can anyone suggest a fix
please?

The problem is that your pattern doesn't start out by confirming that 
it's either at the start of a line or after whitespace. You could do 
this with a look-behind assertion if you wanted.

Hi,

thanks for the advice guys.

Well took the kids swimming, watched some TV, read your hints and
within a few minutes had this:

r = re.compile(r'[EMAIL PROTECTED]@\s]+\.\w+')

This works for me. That is if you have an invalid email such as
tony..bATblah.com it will reject it (note the double dots).

Anyway, now know a little more about regexps :)

Thanks again for the hints,

A little more is unfortunately not enough. The best advice you got was
to use an existing e-mail address validator. The definition of a valid
e-mail address is complicated. You may care to check out Mastering
Regular Expressions by Jeffery Friedl. In the first edition, at least
(I haven't looked at the 2nd), he works through assembling a 4700+ byte
regex for validating e-mail addresses. Yes, that's 4KB.  It's the best
advertisement for *not* using regexes for a task like that that I've
ever seen.

John

The best advice I've seen when people ask How do I validate whether
an email address is valid? was Try sending mail to it.

It's both Pythonic, and truly the best way. If you actually want to
confirm, don't try to validate it statically; *use* the email address,
and check the result.  Send an email to that address, and don't use it
any further unless you get a reply saying yes, this is the right
address to use from the recipient.

The sending system's mail transport agent, not regular expressions,
determines which part is the domain to send the mail to.

The domain name system, not regular expressions, determines what
domains are valid, and what host should receive mail for that domain.

Most especially, the receiving mail system, not regular expressions,
determines what local-parts are valid.

If you have a story of unusual personal hardship that led to the
balances, share it--you may get more response.  

If you're just a usual idiot without the discipline to live within
their their means, get a job, or if you have one, get a better one and
dig yourself out of the whole you've created for yourself.  Otherwise,
we'd all just be enabling you to be an idiot again, we'd all be a
dollar poorer, and you'd be no wiser--just with a better credit score
for a time.

If you're just seeing how many folks will give you money without any
good reason (i.e. not a scam, just an internet beggar), hey, enjoy. 

If you're a clever sociology graduate student doing a pootentially
interesting thesis on various responses to an anonymous plea for money
on the internet, kudos.  I bet it'd be an interesting study.
