Errors not printing correctly (improvised version)

import math


def split_check(total, numofpeople):
    if total <= 0.01:
        if numofpeople <= 1:
            raise ValueError(
                'more than 1 person is required to split the check')
        raise ValueError('Check must be more than $0')
    return (total / numofpeople)


try:
    total = float(input('What is the total? '))
    numofpeople = int(input('How many people? '))
    amount_due = split_check(total, numofpeople)
except ValueError as err:
    print('Oh no! Thats not a valid value, try again...')
    print(f'({err})')
except ZeroDivisionError:
    print('There can\'t be 0 people')
else:
    print(f'Each person owes ${amount_due}')

Since you want to check the number of people AND the amount due, the tests should be sequential instead of nested. Also, since a "raise" will end the function, only the first issue encountered will be displayed. To display both, you'd need to add some additional code to check for both conditions at once before checking for them individually.
