Answer
Use cProfile, profile, or timeit.
Use line_profiler for detailed bottleneck analysis.
Optimize slow loops and hotspots.
Use line_profiler for detailed bottleneck analysis.
Optimize slow loops and hotspots.
Quick Answer
Python profiling: cProfile for production profiling (low overhead). line_profiler for line-by-line: decorate with @profile, run with kernprof -l. memory_profiler for memory: decorate with @profile, run with python -m memory_profiler. py-spy for sampling production processes (no code changes needed). Visualize cProfile results with snakeviz. Profile, find the bottleneck, optimize, measure again.
