Does this code snippet work for making the code reusable? 

import math 

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

def check_total():
    try:
        total_due = float(input("What is the total?  "))
        number_of_people = int(input("How many people?  "))
    except ValueError:
        print("Oh no! Please give me a valid value, try again.")
        check_total()
    else:
        amount_due = split_check(total_due, number_of_people)
        print("Each person owes ${}".format(amount_due))

check_total()

Hey there Bradley Gonzalez !

I just copied your code and ran it, toyed around with it, tried to break it and it seems to be working great! I'd say you did a great job making it reusable :smiley: Well done!

Not when you enter a Zero. It returns:

Traceback (most recent call last):
File "/home/treehouse/workspace/practice.py", line 17, in <module>
check_total()
File "/home/treehouse/workspace/practice.py", line 14, in check_total
amount_due = split_check(total_due, number_of_people)
File "/home/treehouse/workspace/practice.py", line 4, in split_check
return math.ceil(total / number_of_people)
ZeroDivisionError: float division by zero
