Fix is always available.

This rule is unstable and in preview. The --preview flag is required for use.

What it does

Checks for extraneous whitespace after a comma.

Why is this bad?

According to the black code style, commas should be followed by a single space.

Example

a = 4,    5

Use instead:

a = 4, 5
