noob question about unused variable in python

Hi,

I've only started programming recently
and got very interested in the idea
of writing elegant and efficient codes

my question is..
what happens to unused variables in a function
that exits due to an error (value error, index error, etc)?

If by used you mean there was memory allocated, they get cleaned up just like any other variable

yep,, that's what i meant

so that means whenever the function exits, all unused variables will be cleared from the memory?

On exit any allocated memory will be released.

Python is pretty good with its memory management
