What are the best practices for timing code execution in Python?

To time code execution in Python, you can use the time module or the timeit module. The timeit module is generally preferred for measuring execution time because it avoids common pitfalls like background processes affecting the timing.

Can you show me an example using the timeit module?

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}')

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

You can use the time module for that. Here's how:

import time

start_time = time.time()
# Your code block here
end_time = time.time()
print(f'Execution time: {end_time - start_time}')
