[Tutor] Question about profile.run() and decorators

[Thane.Frivold at nokia.com]

Kent,

	Thank you. 

	That was just the kind of hint I needed. I will make sure to
look for objects inside imported packages in the future too; I missed
the Profile attribute when I first ran dir(profile) looking for
available functions.

	In case you archive the full email threads, I have included a
copy of the working program for reference for future neophytes like
myself...

	Cheers,

- Thane

import profile

def myProfileDecorator(function):
  def newFunction(obj, *args, **keywords):
    p = profile.Profile()
    p.runcall(function, *args, **keywords)
    p.print_stats()
  return newFunction

import random

class Foo:
  @myProfileDecorator
  def results(x):
    spin = [x*x for x in range(2000000)]
    print str(x) + " Done"

x = Foo()

print x.results("Almost")
