Activity monitor running, down the list of running processes,
Python shows up with a red 'not responding' comment.
Starting immediately after booting, Python is OK, shortly after
starting 'Mail' it shows up as 'Not Responding'.
Doesn't seem to be causing a problem, but it's a nagging question
--- Why??
The appropriate question is 'what Python script is running'. Python in
and of itself, should not be running, unless some script is running.
Click the Python instance in Activity Monitor, click inspect and see
what the parent process is.
If that doesn't give you a clue, open a Terminal window and run the
command:
sudo lsof
And you will eventually get a long list of open files and the process
that has them open. This way you can track the Python instance to the
script that's hung up.
you can do
sudo lsof > openfiles.txt
and when it's done, open up openfiles.txt and search it.
lsof stands for 'LiSt Open Files' and does exactly what it implies it
lists all open files on the system and the process that has opened
them. It takes a long time, but eventually you get a VERY diagnostic
list of open files:

and on and on and on.
The stuff above is just the basic 'OSX is running' things. The
interesting stuff (from your point of view) is further down, search
that for 'python' or '.py' and see what you can find
