Do you need to declare a separate variable when using parse

Instead of making a whole new variable to represent a number value is it common to just reassign the original prompt and change it from a constant to a variable. I've been noticing this in other people code, I typically try to reassign instead of having too many variables in the code.

Sometimes being conservative with variables can be a tradeoff with maintainability. You'll make a judgement for each situation.

This won't be as much of a concern when you start using functions, since variables created in a function get automatically reclaimed when the function ends.
