Derived from the pyupgrade linter.

Fix is always available.

What it does#

Checks for uses of that set the universal_newlines keyword argument.

Why is this bad?#

As of Python 3.7, the universal_newlines keyword argument has been renamed to text, and now exists for backwards compatibility. The universal_newlines keyword argument may be removed in a future version of Python. Prefer text, which is more explicit and readable.


import subprocess["foo"], universal_newlines=True)

Use instead:

import subprocess["foo"], text=True)
