Re: Choosing a Python IDE. what is your Pythonish recommendation? I do not know what to choose.
Tried every python ide going, they either grind to a halt or just look messy. Best one I ever used and stick with is drpython, years old, probably not maintained but does everything I want at a blistering speed and just looks perfect.

Re: Choosing a Python IDE. what is your Pythonish recommendation? I do not know what to choose.
I want an IDE that I can use at work and home, linux and dare I say windows. Sublime, had to remove it from my work PC as it is not licensed. Atom, loved it until it slowed down. VIM, ok the best if you know vi inside out. Any JAVA based IDE, just slows up on work PC's due to all the background stuff that corporates insist they run. Why can not someone more clever than I fork DrPython and bring it up to date. Its is fast, looks great and just does the job ? Its wx, no idea if that is good or bad but it just works.

Hi Antonio, Just an extra one in case you'll ever want to create a nice GUI, then there's also QT Creator: https://wiki.qt.io/QtCreator_and_PySide A very simple but powerful interface a la XCode... It integrates nicely with PySide: https://wiki.qt.io/QtCreator_and_PySide gr Arno -- https://mail.python.org/mailman/listinfo/python-list This message is private and confidential and may also be legally privileged.

array and struct 64-bit Linux change in behavior Python 3.7 and 2.7
Test case:
import array
array.array('L', [0])
# x.itemsize == 8 rather than 4
This works fine (returns 4) under Windows Python 3.7.3 64-bit build.
Under Ubuntu; Python 2.7.15rc1, 3.6.5, 3.70b3 64-bit this returns 8.
Documentation at https://docs.python.org/3/library/array.html explicitly states
'L' is for size 4.
It impacts all uses types of array (e.g. reading from byte strings).
The struct module is a little different:
import struct
x = struct.pack('L', 0)
# len(x) ===8 rather than 4
This can be worked around by using '=L' - which is not well documented - so
this maybe a doc issue.
Wanted to post here for comments before opening a bug at
https://bugs.python.org/
Is anyone seeing this under Debian/Ubuntu?

RE: array and struct 64-bit Linux change in behavior Python 3.7 and 2.7
Thanks for all the replies (and apologies for top posting, I have a brain dead
email client ☹).
I think the consensus from the various threads is that the docs are either
lacking or misleading.
I mentioned that this impacts bytes and the problem there is more telling as it
hard fails (this is how I first discovered this was an issue):
>>> array.array('L', b'\0\0\0\0')
Traceback (most recent call last):
File "", line 1, in
ValueError: string length not a multiple of item size
I don't believe the documentation is accurate by using the word "minimum".
Minimum would suggest that it would accept a 4-byte value as a minimum and on
64-bit it does *not*, it hard fails. If it were to document that, "the sizes
are native integer types for the platform, the table documents some typical but
*not* guaranteed sizes", that would be more clear.
For struct - I think the '<' and '=' non-padding docs could benefit from some
explanation.. I'm not sure what yet 😊
I saw a few suggestions on alternatives for size specifications, I'm definitely
in favor of that (right now I'm probing I and L to determine size before using
them for real). I don’t think U prefix would work as array really only accepts
a single specifier. If array was to be updated to use multiple character
specifiers I would recommend matching the struct specifier (which it is close
to at the moment) format.
For my uses case I'm seriously thinking about not using array moving forward
and only using struct. I briefly wondered about ctypes (it has nice names, e.g.
c_int64 that are unambiguous) but then I remembered it is not available in
Jython).
With the benefit of hindsight it would have been better if array (and struct)
used stdint.h types, those types and lengths are explicitly documented.
Regarding Barry's comment, yep size consistency with array is a pain - what I
implemented as workaround is below (and likely to be my solution going forward):
x = array.array('L', [0])
if x.itemsize == 4:
FMT_ARRAY_4BYTE = 'L'
FMT_STRUCT_4BYTE = '

Actually, you DON'T have exact control with those sizes, it just happens that
