What is wrong with this code?

-----------------------------------original code---------------------------------------------------

import math
def check(people,bill):
    return (math.ceil(bill / people))

try:
    bill_due = float(input("What is the total?"))
    number_of_people = float(input("How many people are eating today?"))
except ValueError:
    print("Please input a number and try again.")

except ZeroDivisionError:
    print("Please enter more than 0 number of people")

else:

    amount_due = math.ceil(bill_due / number_of_people)

    print("Each person owes {}"   .format(amount_due))

ZeroDivisionError: float division by zero

----------------------------my question----------------------------------------------------------

I was expecting the string"Please enter more than 0 number of people" would show on the console, but instead, there is this warning. What is wrong with my code?

Looking closely at the error message, the ZeroDivisionError is raised during statement execution within the else: code block. Since this is after the except statement it is not caught. You could move the amount_due statement inside the try block or wrap the amount_due statement in its own try statement.

Post back if you have more questions. Good luck!
