My shuffle

The random module's shuffle method mixes up (shuffles) the elements of a list in place, thus its return value is None. Because of this we cannot contract several operations, so for instance we cannot express easily the following: "shuffle the elements of the list and then return with the last element" ( random.shuffle(list1)[-1] ).

Exercise

Create a function called my_shuffle, which returns with the shuffled list, making an operation like this possible: my_shuffle(list1)[-1] .
