unrecognized-platform-name (PYI008)#

Derived from the flake8-pyi linter.

What it does#

Check for unrecognized platform names in sys.platform checks.

Note: this rule is only enabled in .pyi stub files.

Why is this bad?#

If a sys.platform check compares to a platform name outside of a small set of known platforms (e.g. "linux", "win32", etc.), it's likely a typo or a platform name that is not recognized by type checkers.

The list of known platforms is: "linux", "win32", "cygwin", "darwin".


if sys.platform == "linus":

Use instead:

if sys.platform == "linux":
