10 Python Debugging Tips That Will Save You Hours
10 practical Python debugging techniques most developers skip — from pdb to better print debugging, breakpoints, and AI-powered root cause analysis.
Most Python Debugging Is Slower Than It Needs to Be
The average developer spends 30-50% of their time debugging. These 10 techniques cut that time down.
1. Use breakpoint() Instead of print()
In pdb: p order to print, n for next, c to continue, q to quit.
2. pp in pdb for Readable Output
3. locals() and vars() to Dump Current Scope
4. Trace Errors With traceback
5. Use assert as Inline Sanity Checks
6. logging Instead of print() in Long-Running Code
7. time.perf_counter() for Performance Debugging
8. Read Stack Traces Bottom-Up
The crash is the last frame before the error message. Start there, not at the top.
9. Use Type Hints + mypy to Catch Bugs Before Runtime
Run mypy your_file.py to catch type errors statically.
10. When Manual Debugging Isn't Enough
Press Ctrl+Shift+P in VS Code with DebugAI — it reads your full stack trace, queries your local codebase, and returns 3 ranked fixes in under 10 seconds.
