This version would allow there to be '=' in the middle of the string (albeit, such would not be base64, but some other kind of thing). Obviously, I've managed to program Python without this switch for 20+ years. But I think I'd use it occasionally. Currently, I'd probably program my intention like this. Let's assume this is something where the '=' is allowed in the middle. if salt.endswith("=="): salt = salt[-2:] elif salt.endswith("="): salt = salt[-1:] assert not salt.endswith("=") The version you suggested, as mentioned, would not handle a format where '=' was permitted in the middle. -- The dead increasingly dominate and strangle both the living and the not-yet born. Vampiric capital and undead corporate persons abuse the lives and control the thoughts of homo faber. Ideas, once born, become abortifacients against new conceptions.
