What it does#
Checks for repeated equality comparisons that can rewritten as a membership test.
Why is this bad?#
To check if a variable is equal to one of many values, it is common to

foo == "bar" or foo == "baz").
Instead, prefer to combine the values into a collection and use the

If the items are hashable, use a
set for efficiency; otherwise, use a
