Python Formatter

Instructions & Python Knowledge

How to use this tool

• Auto Response: Paste or modify the code in the left input box, and the system will automatically format it for you after you stop typing.
• Safe Formatting: Since Python strictly relies on indentation, this tool provides safe PEP 8 style beautification (removing trailing spaces, cleaning up extra blank lines, standardizing the number of blank lines above and below top-level classes/functions, etc.), which will not destroy your original business logic structure.
• Save Locally: Supports syntax highlighting and allows you to directly save the processed result as a local .py file.

Python Code Specifications (PEP 8)

• Indentation: It is recommended to use 4 spaces for indentation (instead of Tab).
• Blank Lines: Top-level function and class definitions should be separated by two blank lines; method definitions inside a class should be separated by one blank line. This tool automatically integrates this optimization feature.
• Trailing Whitespace: Avoid leaving useless whitespace characters at the end of a code line. Formatting will automatically clear them.
