Derived from the refurb linter.

Fix is always available.

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

What it does

Checks for consecutive global (or nonlocal) statements.

Why is this bad?

The global and nonlocal keywords accepts multiple comma-separated names. Instead of using multiple global (or nonlocal) statements for separate variables, you can use a single statement to declare multiple variables at once.

Example

def func():
    global x
    global y

    print(x, y)

Use instead:

def func():
    global x, y

    print(x, y)
