How to use timeit module

Question

I understand the concept of what timeit does but I am not sure how to implement it in my code.

How can I compare two functions, say insertion_sort

Answer 1

I find the easiest way to use timeit is from the command line:

Given test.py:

def InsertionSort(): ...
def TimSort(): ...

run timeit like this:

% python -mtimeit -s'import test' 'test.InsertionSort()'
% python -mtimeit -s'import test' 'test.TimSort()'
