How can 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 to compare the performance of different approaches.

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(f'Execution time: {execution_time}')

What does the 'number' parameter do?

The 'number' parameter specifies how many times to execute the code snippet. In the example, the function is run 1000 times to get an average execution time.

Can I use timeit with a lambda function?

Yes, you can use timeit with a lambda function. Just pass the lambda as the first argument. For example:

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