autopep8 is a Python source code formatter that automatically corrects formatting problems identified by pycodestyle. It helps developers bring existing code into closer alignment with the PEP 8 style guide.
Rather than applying one fixed formatting style, autopep8 identifies specific violations and attempts to correct them. Developers can control which categories of problems are addressed and how aggressively the formatter modifies source code.
The program is useful for improving the consistency of existing projects without requiring an extensive manual cleanup. It can process individual source files or larger collections of code, and provides configuration options suitable for automated development workflows.
This is free and open source software.
