How can I measure the execution time of a function in Python?

You can use the timeit module in Python to measure the execution time of small code snippets. Would you like an example?

Yes, please provide an example of how to use it.

Sure! Here's a simple example:

import timeit

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

execution_time = timeit.timeit(my_function, number=1000)
print(f'Execution time: {execution_time}')

This will measure how long it takes to run my_function 1000 times.

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

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

execution_time = timeit.timeit('sum(range(100))', number=1000)
print(f'Execution time: {execution_time}')
