Is it necessary to create the function split_check?

In this video we define a new function split_check. I don't fully understand why we need to do that though, I tried the code like this and it's working the same way:

import math
total_due = float(input("What is the total?    "))
number_of_people = int(input("How many people?   "))
amount_due = math.ceil(total_due/number_of_people)
print("Each person owes ${}".format(amount_due))

Are there just multiple ways to write the code for the same results?

You want to use a create a function because it let the code to be reuseable and maintable. for instance lets say I have 3 group of people i want to split their checks 3 times. If we go like that ull have to copy paste this code 3 times. if ull use a function

def splitcheck():
  total_due = float(input("What is the total?    "))
  number_of_people = int(input("How many people?   "))
  amount_due = math.ceil(total_due/number_of_people)
  print("Each person owes ${}".format(amount_due))

splitcheck() then i can just call this function 3 times and all the code inside it will be executed.
