# All you have to do in this exercise is write a good comment that explains
# what local variables are. You should also give an example of a function
# and what the local variables are, and what the scope is of the variable.
# The local variables are variables that are declared inside of a function or loop. Since they are declared inside of the function, they belong only to that one function and no other functions.
# scope of a variable is its lifetime in the program. The scope is variable the block of code in the entire program where the variable is declared, used, and can be modified.
