Print debugging funguje, ale je pomalé. Breakpointy, step-through, profiling — profesionální nástroje pro profesionální debugování.

breakpoint() — vestavěný debugger¶

def process_data(items): for item in items: result = transform(item) breakpoint() # Zastaví zde — pdb prompt save(result)

Python Debugging — Techniques and Tools¶

VS Code debugging¶

// .vscode/launch.json { “configurations”: [{ “name”: “Python: Current File”, “type”: “debugpy”, “request”: “launch”, “program”: “${file}”, “console”: “integratedTerminal” }] }

Profiling¶

cProfile¶

python -m cProfile -s cumulative myapp.py

line_profiler¶

@profile def slow_function(): …

kernprof -l -v myapp.py¶

Key Takeaway¶

breakpoint() pro quick debug, VS Code pro step-through, cProfile pro performance. Přestaňte používat print().
