Returning More Than One Value

A function can return more than one value at once, separated by commas — then you "unpack" them into separate variables when you call it:

def min_max(a, b):
    if a < b:
        return a, b
    else:
        return b, a

smaller, bigger = min_max(9, 3)
print(smaller)
print(bigger)

prints:

3
9

Your turn: we've already read two numbers into a and b for you. Define min_max(a, b) that returns the smaller value first, then the bigger value. Call min_max, unpack the results into smaller and bigger, and print each on its own line.
