Have you had practical experience in analyzing and optimizing code performance?

Yes, within Python projects, I worked on analyzing and optimizing code performance. I used profilers such as cProfile and line_profiler to identify bottlenecks. After analysis, I optimized algorithms, reduced function calls, and applied more efficient data structures.

Example of using cProfile:

import cProfile

def slow_function():
    total = 0
    for i in range(1000000):
        total += i
    return total

cProfile.run('slow_function()')

I also used caching of results with functools.lru_cache and avoided unnecessary input-output operations, which significantly improved response times and reduced system load.
