John Carmack on mutable variables

Dumb question from a primarily Python programmer who mostly writes (sometimes lengthy) scripts: if you have a function doing multiple API calls - say, to different AWS endpoints with boto3 - would you be expected to have a different variable for each response? Or do you delete the variable after it’s handled, so the next one is “new?”

I think renaming an old variable is a common and sensible way to free a resource in python. If there are no valid names for a resource it will be garbage collected. Which is different in languages like C++ with manual memory management.

John Carmack is a C++ programmer apparently that still has a lot to learn in python.

But wouldn't you do that inside a function or a loop body?
