Returning a Value

return sends a value back to wherever the function was called, so you can store it or use it:

def double(n):
    return n * 2

result = double(5)
print(result)

prints: 10

Your turn: we've already read a number into n for you. Define a function double(n) that returns n * 2 (don't print inside the function), then print what double(n) returns.
