Unfortunately the automatically-generated bindings, while fast and complete, are not quite as pythonic as the old PyGTK bindings were. The abstraction layer pygobject provides leaks some of the underlying C-isms through. I can't remember exactly which bits feel the most foreign as it's been a while since I used it. But who am I kidding? PyQt (my preferred toolkit) or PySide aren't terribly Pythonic either; lots of C++ and Qt abstractions leaking through various Qt types when native Python types would be preferable (like lists and dictionaries). -- https://mail.python.org/mailman/listinfo/python-list

In that case, it was the inertia of the existing body of code using the API names which gave justification to reject renames. I would expect that was significant also in the decision not to change the ‘logging’ API names. -- \ “[F]reedom of speech does not entail freedom to have your ideas | `\accepted by governments and incorporated into law and policy.” | _o__) —Russell Blackford, 2010-03-06 | Ben Finney -- https://mail.python.org/mailman/listinfo/python-list

Further to the above the following page:-
https://docs.python.org/3/library/othergui.html
Seems to muddy the water even further as the links don't *seem* to
take one to the places one would expect them to go to. The PyGObject
link goes to https://wiki.gnome.org/Projects/PyGObject and the PyGtk
link goes to https://pygobject.readthedocs.io/en/latest/ which would
also appear to be pygobject.

How to decide (and know) which Python GTK version to use?
I want to decide which is the 'best' Python GTK to use on my Linux
(xubuntu) systems. There seem to be quite a few versions of Python
GTK bindings out there and I'm confused!
I wrote a Python GUI program a little while ago that uses Python GTK
with:-
import gtk
I *think* this is probably GTK 2, or something. I can't find the
proper documentation for this. Is it old/obsolescent?
I'm just starting to write another program now and I seem to be using
GTK 3 (maybe!) by doing:-
import gi
gi.require_version('Gtk', '3.0')
from gi.repository import Gtk
Is this the right/best place to be?
I know this is a bit of a "how long is a piece of string" question but
some guidance would be very welcome. The stuff I write is purely for
my own use and will only ever run on Linux (mostly xubuntu but also
some other Debian derived systems such as Rasbian and Debian on
Beaglebone).

RE: Python bug in ArcGIS - Urban Network analysis tool
A note that Arc may have installed its own version of Python, which it is using from within its own tools. For example, I've got a full Python installation in C:\Python27\ArcGIS10.2 which Arc installed on top of a preexisting installation in C:\Python27. So you may need to explicitly run it with that version to get it to work and to import arcpy ok. ie instead of just running... pydevd.py or... python pydevd.py You might need to explicitly do... C:\Python27\ArcGIS10.2\python.exe pydevd.py ...or the equivalent of wherever it installed it on your system. -Original Message- From: Python-list [mailto:python-list-bounces+david.raymond=tomtom@python.org] On Behalf Of ?

Why did logging not undergo PEP8 API change?
In the run-up to Python 3, the threading module's API went from a Java-reminiscent set of names to a PEP-9 set of names, so threading.currentThread became threading.current_thread. Also (though they didn't get a change in case), some of the set/get methods in threading.Thread received the property treatment with admonition in the module documentation to use the property style. Why wasn't the logging package similarly updated? I imagine there might have been some python-dev discussion about this, but have yet to find anything. I found this thread here from 2009: https://mail.python.org/pipermail/python-list/2009-April/thread.html#533823 There was some discussion of the idea (before the thread predictably wandered off into the weeds). I've not found anything else obviously related to the topic. Perhaps it was nothing more than that the threading module had a PEP-8 champion while logging didn't?

Re: `import somemodule` does not check all paths in `sys.path`
Note that in the `sys.path`variable the path is given as absolute path (I only
wrote it relative to `~` in the in my post, but in the script the absolute path
is used everywhere). See line 2:
```
['/home/pyuser/.homeassistant',
'/home/pyuser/.homeassistant/deps/lib/python3.7/site-packages',
'/home/pyuser',
'/usr/local/lib/python37.zip',
'/usr/local/lib/python3.7',
'/usr/local/lib/python3.7/lib-dynload',
'/home/pyuser/.local/lib/python3.7/site-packages',
'/usr/local/lib/python3.7/site-packages']
```
Also by the time the import happens, the directory is existing. It is not
existing from the beginning, but I also tried calling
`importlib.invalidate_caches()` after installing the packages, which should
force python to check the directories again.
Another interesting thing that I found out is that if I use the (now
deprecated) `imp.find_module('sqlalchemy')` it returns the correct path.
However if I do the same with `importlib.util.find_spec('sqlalchemy')` the
package is not found! (`importlib` is the suggested replacement for `imp`).
To me it really looks like a bug in `importlib`.
