at 4:20 Craig says this is the case but what part of the code is doing that? Wouldnt we need a line similar to amount_due = cost per person? Thanks

Python Development Techdegree Graduate 9,409 PointsHi Andrew!
The function split_check takes two arguments:
def split_check(total, number_of_people)
Those arguments (total, number_of_people) are used in the variable cost_per_person.
def split_check(total, number_of_people):
cost_per_person = total / number_of_people
return cost_per_person
Then the function returns the operation performed by cost_per_person.
Check out the example below:
def split_check(total, number_of_people):
cost_per_person = total / number_of_people
return cost_per_person
split_check(84.97, 4)
Here, I'm calling the split_check function. It will return 21.25, but that information isn't being stored anywhere.
If I store it in a variable, I can refer to that information later. Like this:
def split_check(total, number_of_people):
cost_per_person = total / number_of_people
return cost_per_person
amount_due = split_check(84.97, 4)
You asked: wouldn't we need a line similar to amount_due = cost per person?
Craig said "our function returned the value cost_per_person, which we stored in amount due." Here's another way to think about this:
"The split_check function calculates cost_per_person, and it returns that information. The amount_due variable stores whatever is returned by split_check.
It doesn't store the cost_per_person variable itself, because that variable is used inside the split_check function."
I hope this helps. Let me know if you have questions!
