[issue38382] statistics.harmonic_mean fails to raise error with negative input that follows a 0

Warren Weckesser added the comment: The premature return on ZeroDivisionError also causes an inconsistency in how types are handled. For example, >>> harmonic_mean([1, 0, "foo"]) 0 We get an error as expected if "foo" occurs before 0: >>> harmonic_mean([1, "foo", 0]) Traceback (most
