Handling emails
Hello I wrote a program which was working on python 2.x. I'd like to go for newer version but I face the problem on how the emails are parsed. In particular I'd like to extract the significant parts of the headers, but the query to the servers had turned in to list of bytes. What could be a method that will parse and return the headers into ascii if I'll pass the headers as bytes. Even I don't know whether I can pass as they arrive to the program. For example if I try: import poplib.POP3 _pop= poplib.POP3(srvr) _pop.user(args[1]) _pop.pass_(args[2]) header =_pop.top(nmuid, 0) This will return a list of bytes string and I don't have idea to process them in order to have a dictionary containing 'from', 'to', 'cc', 'bcc', 'date', 'subject', 'reply-to', 'message-id' as keys. -- goto /dev/null -- http://mail.python.org/mailman/listinfo/python-list
Re: Handling emails
Steven D'Aprano wrote:
First of all: thanks for the reply
header =_pop.top(nmuid, 0)
To parse emails, you should use the email package. It already handles
bytes and strings.
I've read several information this afternoon, mostly are leading to errors.
That could be my ignorance fault :)
For what I could come over, I decided to write my own code.
def msg_parser(listOfBytes):
header={}
for lin in listOfBytes:
try: line= lin.decode()
except UnicodeDecodeError:
continue
for key in _FULLhdr:
if key in line:
header[key]= line
continue
return header
listOfBytes is the header content, whuch id given by
libpop.POP3.top(num_msg. how_much), tuple second part.
However, some line will fail to decode correctly. I can't imagine why emails
don't comply to a standard.
Other than that, I'm not entirely sure I understand your problem. In
general, if you have some bytes, you can decode it into a string by hand:
I see. I didn't learn a good english yet :P. I'm Italian :)
header = b'To: python-list@python.org\n'
s = header.decode('ascii')
s
'To: python-list@python.org\n'
I know this, in case to post the entire massege header and envelope it's not
applicable.
The libraries handling emails and their headers seems to me a big confusion
and I suppose I should take a different smaller approach.
I'll try to show a header (if content isn't privacy breaker) but as the
above example the *_pop.top(nmuid, 0)* won't go into your example
If this is not what you mean, perhaps you should give an example of what
header looks like
The difference is that previous version returning text strings and the
following processes are based on strings manipulations.
Just to mention, my program reads headers from POP3 or IMAP4 server and
apply some regex filtering in order to remove unwanted emails from the
server. All the filters treating IO as ascii string of characters.
I passed my modules to 2to3 for the conversion to the newer python, but at
the first run it told that downloaded header is not a string.

Converting a set into list
Hello
I've stumble to find a solution to get a list from a set

aa
['a', 'b', 'c', 'f']
set(aa)
{'a', 'c', 'b', 'f'}

Do you notice the similarity to converting a list to a set?
There was something confusing me yesterday in doing that, but (for me

The point was that after a result from:
newset= set(myset1) set(myset2)
list= [newset]

Probably list(set) is not like [set].

Py3k,email header handling
Hello, some time ago, I wrote a program to eliminate undesided emails from the server(s) and leave those which comply to certain filter criteria. I started it when I got to know whit Python 2.3. Now a days I'd like to spend some time to improve it, just for my interest, however it didn't gather anybody's interest before. Now python 3.2 (and some version before) started to use byte, rather than text strings, almost for all data handling in compliance to unicode. My problem arise that my program handle text strings, so I'd like to rewrite the code My program reads from IMAP4 or POP3 server, I'd prefer that a function/class will return either a list or a dictionary which contains the following fields: 'from', 'to', 'cc', 'bcc', 'date', 'subject', 'reply-to', 'message-id' The list may be organized as tuple (from, its_content,), etc,etc for each field, but I think dictionary would be more efficient to use. 1) is there a way to call the IMAPlib or POPlib and pass the data directly to email.parser.HeaderParser to achieve my intention? 2) If the above will do, do re.compile compile unicode results? I guess yes. 3) any related documentation... -- goto /dev/null -- http://mail.python.org/mailman/listinfo/python-list

I'm afraid I don't understand the question.
Making an example :
from poplib import POP3 as pop3
pop3.user('userid')
pop3.pass_('password')
numMsg, total = pop3.stat()
for cnt in numMsgs:
header = pop3.top(cnt)
# here I'd like to pass the header to some function that will return

The same would be from the IMAP4 message parsing. Some different process
would take, would it ?

A suggestion for an easy logger
Hello, I've resumed my hold project and I like to convert it for py3k2. My knowledge has stagnated at version 2.4, then I found some improvements, but it will take me some time before I get used to. I was using this logger = class log: It outputs lists and strings on file or any possible device that allows write mode. Options are: output file writing mode and special end of line (EOL) def __init__(self, output= None, mode= 'w', lsp= EOL): Can instantiate even no output is given. Choose to build an open file object to append to, or new and give a different line separator self.lsp = lsp self.output= output self.mode= mode try: self.output= open(output, self.mode) except (IOError, TypeError): self.output = None def logger(self, strng, allowed=None): # without any output will simply send log to nowhere :-) if not allowed and not self.output: return # no allowed to write the output # keep silent even temporary skip writing # if allowed, it will go to stderr if isinstance(strng,list): a= EOL.join(strng)+ EOL strng = a strng= strng.replace(EOL,self.lsp) # when not allowed just return if allowed is None: return if strng == '?close?': try: # try to close the file self.output.close() return except IOError: return # silently ignore the failure if self.output and Exists(self.output): self.output.write(strng) else: sys.stderr.write(strng) sys.stderr.flush() return = It is somehow convulitive, isn't it? I do believe the builtin *print* would do more better than my logger. Basically I would like a class which shoudl do: 1) print to stdout either with or without carriage return 2) writing to a file 3) Skip some output Everything should do according to the caller.

Hard to understand 'eval'
Hi,
It seems to be strange that give me syntax error inside an eval statement.
I'm looking at it carefully but I can't see any flaw.
Here it's part of the code:
for nn in stn_items:
value= eval('cp.%s' %nn)
if value and (nn in 'log, trash, multithread, verbose, download'):
cfl[wchkey][nn]= chkbool(value)
continue
if value:
cnfg= 'cfl[wchkey][nn]= _%s(value)' %nn
eval(cnfg)
And the output on pdb:
(Pdb) p cnfg
'cfl[wchkey][nn]=_append(value)'
(Pdb) p cfl[wchkey][nn]
False
(Pdb) eval('cfl[wchkey][nn]= _append(value)')
*** SyntaxError: invalid syntax (string, line 1)
(Pdb) p value
'230k'
(Pdb) p nn
'append'
Obviously I've an _append() function to convert into decimal the given value.
Other eval before this not issuing problems and also rather complicated,
but I'm not seeing the error here.
I'd like to study a class that might get a string and convert it into
function, once it's found inside the program.

I've to go for pdb because it isn't affected by that problem, but also in some case pdb doesn't recognize a fix after a post-mortem restart. The funny thing is that it shows the line corrected, but pdb execute the one it put in memory. However, I think also python shell has such flaw. I'd like to know how to blank all current data and restart a program or re-import a corrected class sentence. Any other to try?

My fight with classes :)
Hi,
I'm very new with classes. I still reading something around ;)
I got started to try a concatenation of 2 type of string, which have a
particular property to start with A or D.
My class here:
Small class to join some strings according to the leading first
letter
def __init__(self):
self.valueA= ''
self.valueD= ''
def __add__(self, value):
if not isinstance(value, str): return
if value.lower().startswith('a'):
self.valueA += value
if value.lower().startswith('d'):
self.valueD += value
return self.valueA ,self.valueD
__call__= __add__
__iadd__= __add__
my test on the shell:
from utilities import StrJoin as zx
k= zx()
k
utilities.StrJoin instance at 0x9dc7ccc
k +'aks'
('aks', '')
k +'daks'
('aks', 'daks')
k +'hdaks'
('aks', 'daks')
k +'dhks'
('aks', 'daksdhks')
j('boi')
Traceback (most recent call last):
File stdin, line 1, in module
NameError: name 'j' is not defined
k('boi')
('aks', 'daksdhks')
k('aboi')
('aksaboi', 'daksdhks')
k('duboi')
('aksaboi', 'daksdhksduboi')
k += 'liu'
k += 'aliu'
Traceback (most recent call last):
File stdin, line 1, in module
TypeError: can only concatenate tuple (not str) to tuple
k
('aksaboi', 'daksdhksduboi')
Do I miss something?
I'd rather like to avoid class, but a function won't allow me to store so
easily data between several call.
Mostly I'd expect to pass to the built instance in a more elaborated
function. Then I mean call will be the primer goal.

Re: catastrophic regexp, help!

I think that I shouldn't put anything around the phrase you want to find.
patzln = re.compile(r'.*(zlatan ibrahimovic){1,1}.*')
this should do it for you. Unless searching into a special position.
In the other hand, I'd like to understand how I can substitute a variable
inside a pattern.
if I do:
import os, re
EOL= os.linesep
re_EOL= re.compile(r'[?PEOL\s+2\t]'))
for line in open('myfile','r').readlines():
print re_EOL.sub('',line)
Will it remove tabs, spaces and end-of-line ?
It's doing but no EOL :(

Re: ConfigObj quoting issues

This error is because of the presence of \', \, \n etc.
I had to do the following to make it work.
address[i].replace(\','').replace('\','').replace('\n','')
it's rather ugly :)
I suggest use re module as follow:
import re
address[i] = re.sub('(`||\n)',re.MULTILINE,address[i])
if you've a big chunck of email it'd be fine to compile the regex.
match = re.compile(`||\n)
address[i] = match.sub(address[i])
I think there would be a problem with unicode email addresses. But I doubt
the existance of unicode addresses nowadays.
Unsure for the syntax, pls check

^^^ according your version, but they're quite the
same

Shed my a light :)
Hi,
I using eval for quite strange reason, as long as I don't know a different
way to implement.
An example:
actions= ('print', 'sum', 'divide', 'myfunction')
parameters=(5, 'nothing',5.63, object)
for routines in actions:
routines(parameters)
I'd like to note that actions are string or string expressions of the program
functions or python itself, so I've in my program something like:
for nn in actions:
eval('cp.%s' %nn)
Where cp is an instance.
So I'm asking here whether exist a way that these string become functions
inside my program, without using eval()

for nn in actions:
func = getattr(cp, nn)
if callable(func):
func(parameters)
I got the point of Duncan and I should remain on evail() because the
evaluation is made on a construct of string expression, which give me the
final name of the function I want to call.
I've tried on Pyshell and clearly said the object str is not callable.
Some of those string are functions inside the module, so I was expecting a
sequence of calls according the passed in functions names, but they *must*
be processed as a python statements ;(

File browser in python gui
hi there, I've started to build a GUI for my Mailsweeper by the help of QT4 Designer. I came across the problem that there isn't any prebuild file browser like Kdialog. I know some other sample, but PyGTK builded. I'm not happy to use a different widget set or to have to design my own file browser with QT4 widgets. It's almost thousand times people need to use such browser, I wonder why I couldn't find one on the entire day searching on web site. A QT XML file (.ui extension) should do fine, if someone would help :) -- Mailsweeper Home : http://it.geocities.com/call_me_not_now/index.html -- http://mail.python.org/mailman/listinfo/python-list
