I want to make this interactive but I am having trouble The code will allow the input but after it gets both pieces it spits this out...

Traceback (most recent call last):
File "check_please.py", line 10, in <module>
amount_due = split_check(bill_total, num_people)
File "check_please.py", line 2, in split_check
cost_per_person = total / number_of_people
TypeError: unsupported operand type(s) for /: 'str' and 'str'

Can someone help me understand what this means? Below is my code

def split_check(total, number_of_people): cost_per_person = total / number_of_people return cost_per_person

bill_total = input("How much was your bill? ") num_people = input("How many people will split the bill? ")

amount_due = split_check(bill_total, num_people)

print("If {} people are splitting the bill that totals {}, \neach person will pay {}.".format(num_people, bill_total, amount_due))

Hey Ethan!

The problem is that the function input() (in python3) returns a string (text). Try converting bill_total and num_people to float (number) and it will be solved ;)

bill_total = float(input("How much was your bill? "))
num_people = float(input("How many people will split the bill? "))

Best Regards!
