Personally, I write a batch file containing the 'python

assumes python.exe is on the Windows path.


Once tested and working it lets me edit the batch file to adjust the 
payload without having to touch the Windows stuff again.

ONE: that path indicates that you installed Python "for current user
only".

TWO: that is the path for the short cut entry that shows up on the
Windows "Start Menu" (whatever that looks like on Win11). It is NOT a
location for user scripts.

Python, at heart, is a language interpreter that is invoked from a
command line shell. (Use  to exit the interpreter if you are trying
the below examples -- otherwise you'd add the path/name of the script file
to the command line)

It can run from scripts invoked by double-clicking on the file in the
"file explorer" but often the results are not as desired (it will pop up a
console window -- but that window closes as soon as the script exits!).
Scripts written using one of the graphical libraries (Tkinter, wxPython,
etc.) are typically given a .pyw extension -- .pyw is normally associated
with an alternate start-up module which suppresses the console window.

Editing of scripts can be done with one's favorite programming text
editor. If one can't live without having some sort of IDE, look for
something called IDLE to be on your start menu (IDLE is actually a Python
script using Tkinter).

Short answer: the same way you would run ANY application at start-up. 

Longer answer: this is a feature of the OS, not Python. You will need
to learn how to use the OS. Maybe start with

The problem is if I post to a mailing list from gmail (either the web
interface or Thunderbird via Google's SMTP servers), Google will
silently discard my own message when the list serv echos it back to me.
In the web-based "conversation" view, Google puts my own sent message in
the conversation. However via IMAP I see nothing.  Thus when looking at
my list mail on Thunderbird, my own messages to the list never show up.

Does that make sense?  There was a lot of fuss about this when gmail
first started doing this, but Google ignored it and continues to ignore
this issue. They regard this sort of email use as "legacy."

Here's an old message describing the problem and showing Google's
non-response:
https://support.google.com/mail/forum/K7un8RUduyrfxS01ac/?hl=en

The only way to prevent this is to send your message via a non-Gmail
SMTP server, and not to put those messages in your Gmail Sent folder.
This runs the risk of messages being flagged as untrustworthy, but as
long as Python's smtp server accepts them, it works.  Of course python's
list messages going out are often flagged as suspicious because they
have our own "from" addresses on them but come through Python's servers.

No the problem has nothing to do with the web interface or the client.
It's a bug/feature of the Google back end.

In Gmail's case it's a matter of not using gmail at all, as their
mailing list -breaking behavior happens whether you use IMAP and
thunderbird.  I work around gmail's breakage right now by using my own
SMTP server for sending messages to the list, so gmail won't recognize
my messages and discard them.

I could leave gmail, but it's not worth it for me at this point.  Python
is the only mailing list left of all the open source projects I used to
follow. It's pretty sad how they all abandoned a format that works very
well for web based formats.

For me, "news" works even better than email, which is why I read all
my email lists via the gmane NNTP server using a news client (slrn). :)

No thanks. I don't want to be on yet another web forum.  I don't need
"social media" or a "social media app."  Email works exceedingly well
for this sort of thing, despite Google's antics.

Sadly a lot of open source projects are abandoning the good old list and
moving to awkward web forums like Discourse.

With e-mail lists, everything is right here in my email client
(Thunderbird), separated out into folders with procmail (or whatever
filtering system you want), and with proper nesting of messages.  No web
forum I've seen offers this convenience or proper nesting.  Electronic
communication is fraught enough. "Social media" (whatever that means)
seems to just make it harder.

You can get the source code from pypi. I don't see any option for pip to
do that, but you can easily do it manually.

If you don't trust the binaries from pypi, don't trust the source code
either! Malware has been found on npm, for example. So to be sure there
are no backdoors you have to (carefully) read the source of each module
you use (which makes the time for downloading them manually trivial).

Oh, and you have read "Reflections on Trusting Trust", I presume?

It's still open source if the source is available (under the usual
conditions). Whether you trust somebody else to compile the software is
a question of trust, not of openness. Do you trust the person who
compiled your compiler?

This is not a place to quarrel our only task is to discuss and help other learn

working on a cryptocurrency project and he might use our original code in his 
final project I don't think offering money is bad. After all there have been

Sending to the list is not a bad thing. We know the OP sent to the list,
because his post appeared on the list :-)

The question is whether he BCCed a bunch of regulars or not.

Unfortunately I deleted the email so I can't look at the headers, but
nevertheless I can categorically say that it didn't come from the mailing
list, because the python-list@python.org mailing list doesn't have my
address. I've always read this though the newsgroup.

I do still have the relevant mail logs:

I'm not an expert, but to me that looks pretty convincing that the email
came directly from Google, not from the mailing list. Am I wrong?

Hi Cameron,

Thanks for your kind reply and suggestion. Sure, please find my question

those edits. Thanks for your support!

I have the following code portion for a convolutional neural network:

Judging from the question on Stackoverflow, I think he's just trying to
drive eyeballs to the question so he can get higher reputation. It is a
silly question: he says he has a pickle file containing an image file, and
he's asking (1) what's in the pickle file, and (2) how can he create an
identical pickle file containing a different image.

The answer to (1) is "Whatever you put in it".

Or possibly malware: he links to an actual pickle file he has put up on-line
somewhere. Anyone brave enough to unpickle it in a sandbox and report on
whether it contains what he says it contains? Remember that pickles can
contain arbitrary executable code.

I do not want to go into the details of your concrete problem --
just give some general remarks about "pickle".

"pickle" is used for serialization/deserialization of (most) Python objects:
i.e. it can transform a Python object into a string (called a "pickle")
and (later) reconstruct the object from the pickle.

You should not be interested in the internal pickle structure --
keep at the Python level.


For your concrete problem: unpickle your pickle file to get
a Python object; construct a similar Python object with the new data;
pickle that Python object.

If you want some help, please, present some code that you wrote and

Re: Python question

[DreiJane]

Hello,

Python and gtk are ambulant (portable plus intallable by mere
copying without admin rights). gtk only needs to have the path to its /
bin on the PATH . The latter could - and possibly should be - done by
the Python scripts using it, for example:

s = os.environ['PATH']
if s.find(gtkBinDir) == -1: os.putenv(PATH, os.getenv(PATH)+
os.pathsep + gtkBinDir)

for gtkBinDir from some GlobalConstants.py.

Pygtk breaks that ambulance - its parts use the registry, but only
for finding Python during installation. Afterwards such a Python is
ambulant again - that means with its pygtk (this little flaw is a
minor reason for me to work on my depikt). I am on Windows normally,
but never considered pywin.

Good luck, Joost

What are you trying to install?

is it available in Synaptic package manager?


If it's a program written in python, then there may be a file called
setup.py. If there is then open a terminal, cd to that directory, and
then type:

python setup.py install

(you may need to do sudo before it) - that will normally automatically

You want the Python Library Reference (quod googla).

If you know the basics of programming already, any old Python tutorial
will do, so just skim through the official one (q.g.) to pick up the
syntax and semantic rules.  Then refer to the Library Reference, which
is well organized and make it easy to track down what you need.  The
libraries come with very good built-in support for tasks 1 and 3; for
2 Python supports timestamp checking and subprocess calling and
whatnot, but stuff like dependency trees you'll have to work out
yourself.

(BTW, if make is failing or annoying you, you might want to consider
SCons, which for me has been a lot more intelligent and

 I think if you've chosen Python as a language to use for these things,
 you could invest some time in learning the language. It is after all

Check out the re module (regexes) in the standard library, and the

 2). Automating my build process

You'll want to look into the os, sys and subprocess modules. The PMOTW
this week was subprocess: 
http://www.oreillynet.com/onlamp/blog/2007/08/pymotw_subprocess_1.html.
A few weeks back it covered os:

In fact one of Doug Hellmann's previous articles on the getopt module
may also be useful if you want your build scripts to be controlled by

(Though I prefer optparse personally).

urllib, urllib2 and cookielib in the standard library should do most
of what you want, perhaps with the addition of beautiful soup if you

That isn't possible without saying what it is that you actually want done.

Besides, the point of specifically choosing Python here for such tasks 
would be your ability to manipulate them and write your own.  If tools 
already exist that do what you need, which languages they were written

Your first sentence suggests that you already know the basics of

figure out for yourself the basic idioms of Python, but learn them from 
code?

In any case, item 1 seems too broad for specific help.  As to item three, 
there are modules and indeed programs available.  Check PyPI on the Python

I can see the point of people who are confused about single file
executables for Python programs, who are possibly new to the technology
and don't know where to look [1] or which questions to ask, and I can
also see the need in various situations for people to make such
executables. That said, I don't buy into the kind of hypothetical ISVs
need this and that pontification seen on places like Planet GNOME,
written by people who work at companies like Novell. The commercial
circuit will use a technology (and, in fact, have been using Python
for some time) when they recognise the genuine benefits of the
technology, and if the technology doesn't deliver exactly what they had
in mind, they'll either put in some effort to shape it to their liking
or they'll look elsewhere. If none of this activity has any community
benefit, I'd argue that there's only so much the community should be
prepared to do to fix such commercial objections - if what a business
wants is valuable enough, that business should be prepared to pay for
it.

 (why are you blaming you inability to use Linux installation tools on
 Python, btw?  most basic Python libraries are only an apt-get away if
 you're using a sane Linux distribution.)

This is true enough, and by packaging one's programs correctly, Python
gets automatically brought into the picture when the user asks to
install those programs. It's interesting to consider this in the
context of the recent Linux Standard Base discussions on python-dev:
LSB potentially mitigates issues with shipping executables across
different distributions and would be beneficial to those wanting to
deploy Python applications in such a way. I notice, however, that the
discussion has taken the peanut gallery position of name-calling and
mock outrage at the packaging practices of various distributions [2],
presumably whilst advocating Python-only solutions like setuptools -
something which really isn't going to work well with any large
heterogeneous collection of software packages. Moreover, the
distributions have to more urgently deal with various issues not yet
sufficiently addressed by the Python core developers, particularly
architecture issues [3] and licensing issues [4].

Freezing applications has been a fairly well-understood process for the
last ten years, but more cooperation with heterogeneous packaging
technologies would be far preferable. After all, distributions are
actually responsible for a large amount of Python usage, and it would
be far better if people actually tried to work with them to resolve
some of the supposedly inflammatory aspects of their packaging
practices rather than just shouting bad things at them from a distance
[5]. A bit of not invented here [6] suppression would also be quite
welcome, along with taking the needs of vendors [7] other than Apple
Computer Inc. into account.

Paul

P.S. And while a frank discussion [7] did appear to result in a
comprehensive exchange of views between Debian and setuptools
developers, I'd like to see a bit more understanding for end-users and
people who don't want to ignore their system's package management.
Python plays well with others is a frequent claim, after all.

Sort of.  Python code is not compiled to machine language.  Instead, it is
compiled to an intermediate language that is then interpreted.  That means
that, at run-time, there must be an interpreter available.

However, there are several packages that will gather up a copy of the
interpreter, your script, and whatever scripts and libraries it might need,
and pack them all into a .exe.  To the end user, it looks like a compiled
program.  py2exe is one example.

Iterating would be the best way.  There are shorter ways of writing it, 
for instance with list comprehensions, but it's still iteration::

for key, value in row:
if key == 'min':
print value
break

or::

results = [v for k, v in row if k == 'min']
print results[0]

Another way, if you plan to access this same data structure in this way 
multiple times before moving on to the next one, would be to turn it 
into a dictionary first::

d = dict(row)
print d['min']

Note that all of these solutions assume that the key you want is indeed 
in there.  If it might not be, then you'll have to gracefully handle errors.
