Question about variable names in functions

In the check please example how does Python know to use the user input from total_due as the total???? Shouldn't the variable be called total?

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))

total_due is passed into split_check() as an argument here:

amount_due = split_check(total_due, number_of_people)

The parameter total of split_check could be named anything (following naming conventions) however the code within the function would have to be updated with the new name. For example:

def split_check(x, y):
  return math.ceil(x/y)

would return the same result

ok I see. The arguments name is unimportant. it's where you place the arguments when calling the function that matters
