Python's random.shuffle uses the Fisher-Yates shuffle, which runs in O (n) time and is proven to be a perfect shuffle (assuming a good random number generator). It iterates the array from the last to the first entry, switching each entry with an entry at a random index below it. The basic process of Fisher–Yates shuffling is similar ...
