consider-merging-isinstance / R1701

Message emitted:

Consider merging these isinstance calls to isinstance(%s, (%s))

Description:

Used when multiple consecutive isinstance calls can be merged into one.

Problematic code:

from typing import Any


def is_number(value: Any) -> bool:
    # +1: [consider-merging-isinstance]
    return isinstance(value, int) or isinstance(value, float)

Correct code:

from typing import Any


def is_number(value: Any) -> bool:
    return isinstance(value, (int, float))
