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”.

Post back if you need more help. Good luck!!!
