How do I compare python functions in terms of performance?

Question

I have written 2 functions doing the exact same thing, but I don't know which one is faster and better. How do I compare these 2 functions to see which one is better in terms of performance and everything?

Answer 1

The timeit module will do ya.

Answer 2

Once you've found out which function is faster using the timeit module, you can also get more precise details of where the differences are by using the profile module.
