How do I keep repeating the loop until i get an answer? I guess while loop but where do I input it?

import math


def split_check(bill, people):       
    amt_due = math.ceil(bill // people)
    return amt_due

try:    
    bill = float(input("What is the total bill? "))
    people = int(input("How many people are there? "))
    call = split_check(bill, people)
except ValueError:
    print("Oh no! Try again")
except ZeroDivisionError:
    print("Has to be more than 1 person")
else:
    print("Each person owes ${}".format(call))

Right before the "try" you could put "while true:", and then indent everything below it to put it inside the loop.

Then after the final "print" you could add a line with "break" so the loop ends when the calculation is successful.
