Valid base64 might end in one, two, or zero '=', but the result wants to have none. Actually, no... even two calls won't always do the right thing. I'm happy to have the new method .cutsuffix() , but I don't think it addresses this case. I was going to suggest an example about dynamically built path components that may or may not end in '/'. However: A. I couldn't find an example in my own code easily, even though I know I've fiddled with that B. Someone would scold me for playing with strings rather than using Pathlib (they'd be right, I realize... but I am sinful in my quick-script ways). I'll let someone else, like the OP, advance the case more. I kinda like it, but it's not a big deal for me. -- 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.
