Follows Python's official style guide with 4-space indentation, proper spacing, and blank lines around functions.

Import Organization

Automatically sort imports alphabetically and group them by standard library, third-party, and local modules.

Quote Normalization

Standardize string quotes to single or double style for consistency across your codebase.

100% Client-Side

Your code stays in your browser. Safe for proprietary Python projects and sensitive data.

How this Python Formatter works

This code beautifier formats Python source code according to PEP 8 style guidelines, the official Python style guide. The formatter analyzes code structure to apply consistent indentation, proper spacing around operators, and appropriate blank lines between functions and classes.

Users can configure indent size (2 or 4 spaces), maximum line length (79, 88, or 120 characters), and string quote style (single or double). The tool handles Python-specific constructs including decorators, comprehensions, lambda expressions, and multiline statements with proper continuation indentation. Import statements can be optionally sorted alphabetically and grouped by standard library, third-party, and local imports.

The formatter preserves docstrings and comments while adjusting the formatting of executable code. Processing uses client-side JavaScript pattern matching rather than a full Python parser, making it suitable for most common formatting tasks without requiring a Python runtime. The output can be copied to clipboard or downloaded as a .py file for immediate use.

Frequently Asked Questions

Does this follow PEP 8 standards?
Yes! The formatter applies PEP 8 guidelines including proper indentation, spacing around operators, blank lines around functions/classes, and more.
What about import sorting?
When enabled, imports are sorted alphabetically and grouped by standard library vs local imports, following PEP 8 recommendations.
Does it preserve my comments and docstrings?
Absolutely. Comments and docstrings (triple-quoted strings) are preserved exactly as written while the code is formatted.
Can I use 2-space indentation?
Yes, though 4 spaces is the PEP 8 standard. The option is available for projects that use different conventions.
Is my code secure?
Yes. All formatting runs locally in your browser. Your code never leaves your device, making it safe for proprietary projects.
