Overview

This is a flake8 plugin which ensures that imports from the typing library must be written using import typing as t.

Installation

pip install flake8-typing-as-t

Checks

• TYT01: Bare import typing usage
• TYT02: import typing as X where X is not literal t
• TYT03: from typing import X usage

Handling typing-extensions

A common pattern for compatibility is to do a sys.version_info-guarded dispatch over typing_extensions. e.g.

if sys.version_info < (3, 8):
    from typing_extensions import Literal
else:
    from typing import Literal

flake8-typing-as-t allows for this usage by checking if the import is inside of a test on sys.version_info against a tuple.
