Return answer

Question

I'm working in this question and I'm not sure why we would return to a variable name. at the end is return answer; it's not making sense how that works.

Answer 1

To further explain Cals explanation..

def add(x,y):
return x+y

simple function that takes in 2 numbers and adds them together. how you use the return is up to you. maybe you want to get the sum of 2 random numbers for an addition program.

num1=random.randint(1,9)
num2=random.randiny(1,9)
sum=add(num1,num2)

print(num1)
print("+")
print(num2)
answer=int(input(("Enter your answer - "))

if answer==sum:
print("You are correct!")
else:
print("Wrong!")

Answer 2

I think I understand it now it's return 0 for main function that's an int and it just needs it's value so return answer is returning the result of the function in the form of a variable

Answer 3

Say you have a function, that adds two numbers. You don't know whether the result will be printed to the screen, written to a file, display in graphics, or used in another calculation. You could write a function for each of these, or you could return the value to be used as it is needed.
