Questions

How do I clean up Python indentation?
Paste your Python code into the input and the formatter will normalize indentation to a consistent number of spaces, fix mixed tabs and spaces, and ensure proper spacing around operators and keywords.
Does it follow PEP 8 style guidelines?
The formatter applies PEP 8-inspired conventions including consistent indentation, spaces around operators, spaces after commas, and blank lines between function and class definitions for readable Python code.
How does this Python formatter compare to Black?
This is a quick browser-based formatter for cleaning up indentation and spacing. Black is a stricter, opinionated local tool that rewrites more of your code style. Use this tool for fast one-off formatting without installing anything.
Does the Python formatter handle decorators and type hints?
Yes, decorators, type hints, f-strings, and other modern Python syntax are recognized and formatted with proper spacing and indentation.
