Python: how to identify error location – any tips for quickly finding where things went wrong? or Str

Python: how to identify error location? My workflow:

1. Run the code.
2. If it crashes, read the *last* line of the traceback first—that’s usually the actual error.
3. Scroll up to see the stack trace and find the file/line.

For bigger projects, `pytest` with `-v` flag shows exactly where tests fail.

Also, `pyflakes` or `flake8` can catch dumb mistakes before you even run the code.
