Profiling a Python Script

Here are some simple ways to profile Python scripts.I heavily use this to check my Project Euler solutions.

SOLUTION 1:

The main common option would be to use the profile (or cprofile) module.There are two different ways of using it :

As a module, by directly running

python -m cProfile script.py

In your code, by importing the utilities

import cProfile
cProfile.run('function()') # in your __main__

Bonus : You can use several options for sorting results using the -s switch (cumulative/name/time/file sorting are available).

SOLUTION 2:

If you want to avoid using a command line, or you don't have the profile module installed; here os another possibility. There is also the timeit module available.

import timeit
t1 = timeit.Timer("function()", "from __main__ import function")
print t1.timeit(1)

I use this option on Eclipse because I didn't want to install the profile module on Windows. This is however less clear, and way less detailed while still useful :). Choose you profiler option and get on Project Euler ! [Stack Overflow]
