I've been playing with Python 3.9.0rc1 and was looking at a particular graph to
see when it released tasks for processing.
I ran the following code:
from functools import reduce
from pprint import pprint as pp
from collections import defaultdict
from graphlib

Can we now:
1. Move os.path.commonprefix to str.commonprefix or string.commonprefix
2. Deprecate the use of os.path.commonprefix
3. Add os.path.commonpath
4. Update the documentation.
This seems to have lingered for too long and yet people have been willing

I like R. David Murray's suggestion, but I am also aware of how it works and so
cannot judge how it would look to the intermediate Python programmer who knows

Hmmm. It seems that the problem isn't to do with the fact that it works, or how
to apply it; the problem is with *how* it works.
Making it an idiom means that too many will use it without knowing why it works
which could lead to later maintenance issues. I

In the zip section of the documentation, e.g.
https://docs.python.org/3/library/functions.html#zip There is mention of an
idiom for clustering a data series into n-length groups that I seem to only
come across when people are explaining how it works on blog

Hi,
When I try and use pprint on standard types I get varying 'quality of
output'.
Lists will wrap nicely to multiple lines as will dicts, but sets and
defaultdicts give one long unreadable line.
Is their a chance to get this changed so that more built-in types look
pretty when printed with

Hello All!
I'am novice in python, and I find one very bad thing (from my point of view) in
language. There is no keyword or syntax to declare variable, like 'var' in
Pascal, or special syntax in C. It can cause very ugly errors,like this:

S=0
