You'd have to call cutsuffix twice. 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.
