What is the difference between profiling and benchmarking in Python?

What is the difference between profiling and benchmarking in Python?

Profiling is about measuring the performance of your code to identify bottlenecks, while benchmarking compares the performance of different code implementations.

Can you give me an example of how to profile a Python function?

Sure! You can use the cProfile module. Here's a simple example:

import cProfile

def my_function():
    # Your code here
    pass

cProfile.run('my_function()')

What about benchmarking? How can I do that?

For benchmarking, you can use the timeit module. Here's an example:

import timeit

def my_function():
    # Your code here
    pass

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

Are there any tools that can help with both profiling and benchmarking?

Yes, tools like Py-Spy and line_profiler can help with profiling, while libraries like pytest-benchmark can assist with benchmarking.
