The Bug

I am upstreaming this issue from ruff (https://github.com/astral-sh/ruff/issues/9191), because I did not see any special handling for the operator.contains operand and the test case in this repo is also wrong.

f = lambda a, b: a in b

should be replaced by operator.contains according to rule 118

However, according to the documentation contains is actually equivalent to b in a!

This code snippet will show you that the operands are indeed reversed.

import functools
import operator
f = lambda a, b: a in b
print(functools.reduce(f, ["str", {"str"}]))
print(functools.reduce(operator.contains, ["str", {"str"}]))
