Questions tagged [pep8]

Coding conventions and style guidelines for Python. Not to be confused with the PEP/8 assembly language.

PEP (Python Enhancement Proposals) 8 describes coding conventions for code in the standard Python library. This PEP covers how code should be commented, use tabs or spaces to indent code, naming convention, the use of non-semantic white space, etc.

Many large projects have adopted PEP8 (at least in part) as part of their style guides.

The tool pep8 will report code-conformance to the PEP8 guidelines.

Questions tagged as pep8 should relate to how to apply these guidelines to your code.

The full text of PEP8 can be found at python.org.
