How to do it...

The timeit module provides a bunch of utilities to time a function or whole script:

>>> import timeit

>>> print(
...     timeit.timeit(function1)
... )
10.132873182068579

>>> print(
...     timeit.timeit(function2)
... )
5.13165780401323

From the reported timing, we know that function2 is twice as fast as function1.
