Raise in try block

Is it ok if I move the if and raise within the try block? the code seemed to work fine for me.

import math

def split_check(total_check, number_of_people):  

    return math.ceil(total_check/number_of_people)

try:            
    total_check = float(input("Enter the check amount: "))
    number_of_people = int(input("Enter the number of people: "))
    if number_of_people <= 1:  
        raise ValueError ("We can't split the check.")
    amount_due = split_check(total_check,number_of_people)
except ValueError as err:
    print("Please enter a correct amount!")
    print("{}".format(err))
else:
    print("Each person owns: {}".format(amount_due))

As long as the "raise" occurs within the "try" block, it will work with the "except". That part doesn't matter if it happens inside or outside of the function.

It does make a bit more sense to have it inside the function, because that's where the math is being done.
