I wrote about it on satellite-dept during 2009...

 From my email:
When you want to profile python, just do:
  import profile
and replace
  sys.exit(abs(main() or 0))
with
  sys.exit(abs(profile.run('main()', '/tmp/profile.data') or 0))
or similar for any function you want to profile.

Then:
yum install tkinter
download http://svn.rhndev.redhat.com/viewcvs/trunk/eng/scripts/pprofui.py
and display the data using:
  pprofui.py /tmp/profile.data

That script is grabbed from:
