4,937 PointsHow can I call a function that returns multiple inputs with a function that takes multiple inputs without TypeError?
This may be a little advanced for this lesson. I took the input calls and combined them into a method called "get_input()" that returns multiple values like this:
def get_input():
total_due = float(input("What is the total: "))
amount_of_people = int(input("What is the amount of people: "))
return total_due,amount_of_people
I then called this function with split_check() that accepts two inputs, total and amount_of_people like this:
amount_due = split_check(get_input())
When I did this, I received a TypeError. The only way I have found around this is to capture the results of get_input() using this:
input_total, input_amount_of_people = get_input()
By then calling split_check(input_total,input_amount_of_people), the script runs correctly. Is there a way to call split_check(get_input()) without a TypeError? Would I have to return a tuple or another type from get_input() and accept this new type in split_check()?

def split_check_from_tuple(tup):
return split_check(tup[0], tup[1])
Then you should be able to: "amount_due = split_check_from_tuple(get_input())".

3,581 PointsActually - you're already returning a tuple:
return total_due,amount_of_people
And since you're already returning a tuple, all you need to do is unpack that tuple using the * operator when you send it to split_check:
amount_due = split_check(*get_input())
