debugging

Debugging Python errors starts with capturing the full stack trace and relevant logs to identify where the failure occurred. Gather the exact error message, trace the call sequence, and examine environment context to pinpoint the root cause before forming and testing hypotheses.

Reproduce errors by isolating minimal steps that trigger the failure reliably. Create a small test case with the exact inputs and conditions, verify the error reappears, then use that reproduction to test fixes and confirm the issue is resolved without regression.

Yes. Breakpoints and targeted logs are core debugging techniques for Python. Insert breakpoints at suspected failure points or add logging statements to inspect variable state, then step through execution or review logs to validate your hypothesis about what went wrong.

After implementing a fix, run your test suite to verify the original error is resolved and no new failures appear elsewhere in the codebase. This regression testing ensures your solution is safe and doesn't introduce unexpected behavior in other parts of your application.

Gather the exact error message, full stack trace, relevant code snippets, logs around the failure time, and environment details like Python version and dependencies. This context helps you form accurate hypotheses and test solutions efficiently rather than guessing.
