How do I set up and use the timeit module in Python?

To use the timeit module, you first need to import it. You can then use the timeit.timeit() function to measure execution time.

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

Sure! Here's a basic example:

import timeit

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

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

What does the 'number' parameter do?

The 'number' parameter specifies how many times the code will be executed. In the example, the function runs 1000 times.

Can I use timeit with a lambda function?

Yes, you can! Just pass the lambda function as a string to the timeit function. For example:

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