My question is:
Why False and 1 is False but True and 1 is 1
Likewise, False or 1 is 1 but True or 1 is True
Can someone kindly explain why this is happening

Maybe your data has already been preprocessed (inadequately)? Can you get the raw data? Why do you think ... | 1 | 13 | 1 | I have a Pandas Series, that needs to be log-transformed to be normal distributed. But I can´t log transform yet, because there are values =0 and values below 1 (0-4000). Therefore I want to normalize the Series first.
