global-at-module-level (PLW0604)

Derived from the Pylint linter.

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

What it does

Checks for uses of the global keyword at the module level.

Why is this bad?

The global keyword is used within functions to indicate that a name refers to a global variable, rather than a local variable.

At the module level, all names are global by default, so the global keyword is redundant.
