missing-whitespace-around-operator (E225)

Derived from the pycodestyle linter.

Fix is always available.

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

What it does

Checks for missing whitespace around all operators.

Why is this bad?

According to PEP 8, there should be one space before and after all assignment (=), augmented assignment (+=, -=, etc.), comparison, and Booleans operators.

Example

if number==42:
    print('you have found the meaning of life')

Use instead:

if number == 42:
    print('you have found the meaning of life')
