A flake8 extension that helps to make more readable variables names

Project description


Build Status Maintainability Test Coverage PyPI version PyPI - Python Version

An extension for flake8 that helps to make more readable variables names.

We believe, that variable name should unmistakably shows, what it contains. Thats why we try not to use varnames with only one symbol or not to use too common names, such as result, value or info.

This extensions helps to detect such names. By default it works in non-strict mode. You can change it with --use-varnames-strict-mode parameter end extend variable names blacklist even more.


pip install flake8-variables-names


Sample file:


a = 1
foo = 2
result = a + foo


$ flake8 VNE001 single letter variable names are not allowed VNE002 variable name should be clarified

Error codes

Error code Description
VNE001 single letter variable names like 'XXX' are not allowed
VNE002 variable name 'XXX' should be clarified
VNE003 variable names that shadow builtins are not allowed
