Hi all,
I'm playing with python internals and I'm discovering a strange behavior
of isinstance. Considering the following test case:
test/bar.py
test/b.py
test/a/__init__.py
test/a/foo.py
-- __init__.py -> empty

I'm trying to develop with AF_UNIX socket type in python (2.5) but

Hi
Since upgrading to Python 2.7, I've run into the problem that when I
launch shell scripts (.e.g, *.bat) via subprocess.Popen (with False
for the 'shell' option, mind you), the arguments get interpreted by
the shell. For instance, the '|' character, no longer gets passed
verbatim to the script.

You could try a collections.defaultdict object with an integer as the startup

counts = collections.defaultdict(int)
for thing in long_list:
counts[get_last_two_digits(thing)] += 1
This assumes get_last_two_digits is the function that provides the key you want
to count by. I'm not sure
