BUG (string dtype): logical operation with bool and string failing (original) (raw)

We do allow using logical operators like | to be used with non-boolean data (at which point the non-bool series would be cast to bool, I assume). For example:

ser1 = pd.Series([False, False]) ser2 = pd.Series([0.0, 0.1]) ser1 | ser2 0 False 1 True dtype: bool

This also worked with strings in object dtype:

ser2 = pd.Series(["", "b"], dtype=object) ser1 | ser2 0 False 1 True dtype: bool

but currently fails with the pyarrow-backed string dtype:

pd.options.future.infer_string = True ser2 = pd.Series(["", "b"]) ser1 | ser2 ...
