How do I use the timeit module in Python?

The timeit module in Python is used to measure the execution time of small code snippets. You can use it by importing the module and calling the timeit() function.

Can you show me a simple example?

Sure! Here's a basic example:

import timeit

def test():
    return sum(range(100))

execution_time = timeit.timeit(test, number=1000)
print(execution_time)

This will time how long it takes to run the test function 1000 times.

What if I want to time a specific piece of code instead of a function?

You can use the timeit function with a string of code. For example:

execution_time = timeit.timeit('sum(range(100))', number=1000)
print(execution_time)

Are there any options to set up the environment before timing?

Yes, you can use the setup parameter in the timeit() function to set up any necessary environment or variables before timing your code.
