Python Beautifier
The Python Beautifier fixes indentation issues and formats Python code to be clean and readable. Since Python relies on indentation for code structure (unlike languages that use braces), proper formatting is absolutely critical — a single wrong indent can change program behavior or cause runtime errors. This tool normalizes whitespace, fixes mixed tabs/spaces, and ensures consistent indentation levels throughout your code.

Does it follow PEP 8 style guidelines?
The beautifier normalizes indentation which is a core PEP 8 requirement. The default 4-space indentation matches the PEP 8 standard. For full compliance (line length, naming), use a dedicated linter like flake8 alongside this tool.
Can it fix mixed tabs and spaces?
Yes, the formatter converts all indentation to consistent spaces, eliminating the common 'TabError: inconsistent use of tabs and spaces' that Python developers frequently encounter.
Does it work with Python 3 syntax?
Yes, it supports all Python 3 syntax including f-strings, walrus operators (:=), type hints, match statements (3.10+), and exception groups (3.11+).
