Python PEP8: Remove wildcard imports with explicit imports

[cclauss]

Replace import * imports in Python files with explicit imports.
% pipx run removestar --in-place . # https://www.asmeurer.com/removestar

This change allowed our linter to find and fix an undefined name: HotkeyEvent --> ControlGroupEvent

F821 undefined name 'HotkeyEvent'

This would have raised NameError at runtime.
% ruff rule F821

undefined-name (F821)

Derived from the Pyflakes linter.

What it does

Checks for uses of undefined names.

Why is this bad?

An undefined name is likely to raise NameError at runtime.

Example

def double():
    return n * 2  # raises `NameError` if `n` is undefined when `double` is called

Use instead:

def double(n):
    return n * 2
