Just in case you want a new array you can use sample:

import random
new_array = random.sample( array, len(array) )

ANSWER 4

Score 21

The other answers are the easiest, however it's a bit annoying that the random.shuffle method doesn't actually return anything - it just sorts the given list. If you want to chain calls or just be able to declare a shuffled array in one line you can do:

import random
def my_shuffle(array):
    random.shuffle(array)
    return array

Then you can do lines like:

for suit in my_shuffle(['hearts', 'spades', 'clubs', 'diamonds']):
