A questions about scope in 'while' loops.

So I know there is a global scope and the scope inside the functions, does it apply to while loops? is a variable I am creating inside a while loop is global or unique to this loop?

If it is unique, what do I get if I create a variable in the same name as a global variable, when the the loop runs again will it check my global variable or my unique variable?

While loops do not have their own scope. They share scope with the function they live in. Any variable you create within a while loop is available anywhere within that function.
