I've had this problem before (setting/altering shell variables when
executing a command from Python, albeit using os.system() instead).
What I'd use is:
commands.getoutput('COLUMNS=500 ps ax')
or similar. In your case, you've been able to solve in another way
(and better, since environment independent, though still shell/ps-
variant dependent), but sometimes one may need to set/change shell
variables, like paths to dynamic libraries. The above should work
(for more variables, just specify them all before the actual command,
whitespace separated).
