Since idx is not None here, I think this can be reverted.

Hi! The test on lines 742-743 calls result = df.iloc[np.array([True] * len(mask), dtype=bool)]
tm.assert_frame_equal(result, df)I noticed I should add another test with false values so I have done so. result2 = df.iloc[np.array([True, False, True, False, True], dtype=bool)]
tm.assert_frame_equal(result2, DataFrame({"a": [0, 2, 4]}, index=["A", "C", "E"])) |
