A flake8 plugin to ban type hints.

A flake8 plugin to ban type hints.

This can be useful in code bases where you aren’t running type checking (yet?) but developers or their IDE’s add type hints that can be incorrect.

Requirements

Python 3.6 to 3.10 supported.

Installation

First, install with pip:

python -m pip install flake8-no-types

Second, check that flake8 lists the plugin in its version line:

$ flake8 --version
3.7.9 (flake8-no-types: 1.0.0, mccabe: 0.6.1, pycodestyle: 2.5.0, pyflakes: 2.1.1) CPython 3.8.0 on Darwin

Third, add the NT prefix to your select list. For example, if you have your configuration in setup.cfg:

[flake8]
select = E,F,W,NT
