Simply upload your .py file or paste Python code to get a detailed analysis with line-by-line error reporting and suggested corrections. The tool highlights problematic lines and provides corrected code that follows PEP 8 standards.

Frequently Asked Questions

Find Quick Answers

What Python indentation issues does this tool detect?

The tool detects mixed tabs and spaces, inconsistent indentation levels (e.g., 2 spaces vs 4 spaces), missing indentation after colons, and improper nesting that would cause IndentationError in Python.

Does this tool modify my original files?

No, this is a client-side tool that runs entirely in your browser. Your code is never uploaded to any server, and your original files remain unchanged.

What Python versions are supported?

The tool checks indentation rules that apply to all Python versions (Python 2.x and 3.x) since indentation syntax is consistent across versions.

Can I check large Python files with this tool?

Yes, the tool can handle files of reasonable size. For optimal performance, we recommend files under 10,000 lines of code.
