Python Advanced Profiling and Optimization

This skill provides expert-level knowledge on profiling Python applications to identify performance bottlenecks in CPU and memory usage, and guides evaluation and application of experimental Python 3.13 features.

CPU Profiling with cProfile

cProfile is Python's built-in deterministic profiler, measuring execution time of all functions.

Basic Usage

import cProfile
import pstats

# Profile a specific function
def main():
    # Your application code
    result = expensive_operation()
    return result
