Python Python Basics Functions and Looping Expecting Exceptions

ZeroDivisionError not working?

Just for fun, below my ValueError exception, I tried adding another exception for a ZeroDivisionError. However, if I put in 0 for the number of people who will be splitting the check, I still get the error and the exception doesn't run. Why does my first exception (ValueError) work correctly while my second one (ZeroDivisionError) fails to run the code and instead kicks to the else statement, thus continuing to produce a ZeroDivisionError?

Here's my code:

import math


def split_check(num, amt):
    return math.ceil(amt / num)

try:
    total = float(input("How much was the total bill?  "))
    persons = int(input("How many people are there?  "))

except ValueError:
    print("Oops! Invalid value!")
except ZeroDivisionError:
    print("Invalid input, you need 2 or more people.")

else:
    print(f"Each person owes {split_check(persons, total)} dollars!")

This works as you intended it, I believe:

import math

def split_check():
    try:
        total = float(input("How much is the total bill?  "))
        persons = int(input("How many people are there?  "))

        each_tab = (total / persons)

        print_string = "Each person owes ${:,.2f}".format(each_tab) 

        print(print_string) 

    except ValueError:
        print("Oops! Invalid value!")
    except ZeroDivisionError:
        print("Invalid input, you need 2 or more people.")



split_check()

With 0 persons, "Invalid input, you need 2 or more people." prints

With H for either input, you get "Oops! Invalid value!"

If you input 100.00 for the check, and 4 for the number of people, "Each person owes $25.00" prints out.

By the way, you can easily test it here:

I hope that helps. Stay safe and happy coding!
