Most commonly your program fails this test if you use a print statement
in your sort_hand function. You must not print anything in this function.
Instead, you should return the location so that the test code can access it.

Wrong:

def add(a, b):
    ""\" Add a and b.""\"
    print(a+b)

Right:

def add(a, b):
    ""\" Return the sum of a and b.""\"
    return a+b
