How can I use the timeit module for performance testing in Python?

You can use the timeit module to measure the execution time of small code snippets. It provides a simple way to time your code.

Can you show me a basic example of how to use it?

Sure! Here's a simple 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 directly with a string of code. For example:

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

Are there any options to customize the timing process?

Yes, you can customize the number of executions, the setup code, and more. Check the timeit documentation for advanced options.
