Answer 1

hmm maybe that's because return isn't supposed to output a value but give the function a value back when it's called!Try reading the Python sololearn course.

Answer 2

Because you aren't using any print. print(GCD(int(A),int(B)))

Answer 3

example:

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

add(4,5) - This would return 9 and do nothing with it.

num=add(4,5) - This would set the variable "num" to a value of 9 as 9 is returned from the function

print(add(4,5)) - This would print whatever is returned from the function

Return is simply what information you get back from the function. What you so with that is up to you.

Return = The info sent back from the function
Print = output to the screen

Answer 4

well I did.
what should I change to make it work?
