Have you had experience using tools for analyzing software performance?

Yes, I have used performance analysis tools in Python, such as the cProfile module for profiling code. It helps identify which functions take the most time during program execution.

Example of using cProfile:

import cProfile

def my_function():
    total = 0
    for i in range(10000):
        total += i
    return total

cProfile.run('my_function()')

I am also familiar with visualization tools for profiling results, such as SnakeViz, which help better understand bottlenecks in performance.
