How to use this tool?

Need to fix your Python code fast? This free AI tool takes broken or non-working Python code and returns the complete, corrected version. To use this tool, take the following steps -

  1. Type or upload the broken Python code you want to fix.
  2. (Optional) Paste the error message or traceback you saw, or add any other instructions, e.g. "keep the function signature the same".
  3. Click on the Fix Code button.
  4. Review the fixed code as a diff against your original, or switch to the plain Fixed Code view.

How is this different from the Python Code Checker?

The Python Code Checker is diagnostic-first: it gives you a list of issues to work through, with corrected code as a secondary section. This Fixer flips that: the complete, working Python code is the headline, shown as a diff against what you pasted in, with a short explanation of what changed underneath. If you want the full issue-by-issue breakdown instead, use the Python Code Checker.
