# reason for total and total_due

I don’t understand why I'm creating a total and a total_due what is the difference? CODE FROM LESSON STARTS HERE

```import math

def split_check(total, number_of_people):
return math.ceil(total / number_of_people)

total_due = float(input("What is the total?   "))
number_of_people = int(input("how many people?   "))

amount_due = split_check(total_due, number_of_people)

print("Each person owes \${}".format(amount_due))
``` Hey Stone Currier, good question! The name or label chosen for an object (aka, variable name) is local to the “level of reference” or level of code or scope. The name `total_due` is defined at the top level and belongs the the top-level or module namespace. The name `total` is defined and belongs to the function `split_check` local namespace.
Even if both were named the same, they would not be the same. The function label would reference the same object that the argument label points at. That is, `total_due` points to the result of the equation, and since `total_due` is passed into the function, the local label `total` also points at that same object (the result of the equation).
Think of the function `total` becoming an alias for `total_due`. Even if both were named the same as “total”, it would be the local “total” as an alias for the module “total”.
