Module level functions are local to the module unless imported by
another module.  Nested functions are local to the function they are
nested within unless explicitly returned.  Methods are local to
classes and subclasses.  Lambda expressions are very local unless
somehow passed around.

I am not sure which best meets your intention.

Yes, named objects, including functions can (locally) shadow
(override) builtins.  It is considered a bad habit/practice unless
done intentionally with a functional reason.
