There is a newer version: 4.23.0.17664

Why is this an issue?
Creating a new Exception without actually raising it has no effect and is probably due to a mistake.
Noncompliant code example
def func(x):
    if not isinstance(x, int):
        TypeError("Wrong type for parameter 'x'. func expects an integer")  # Noncompliant
    if x < 0:
        ValueError  # Noncompliant
    return x + 42

Compliant solution
def func(x):
    if not isinstance(x, int):
        raise TypeError("Wrong type for parameter 'x'. func expects an integer")
    if x < 0:
        raise ValueError
    return x + 42
