Card dealing app for Dad

deal.py

"""
Specification:
A function initDeck which creates a list Deck of 52 entries containing the numbers 1-52. Needs to be recallable so delete 
or overwrite Dec.
Second function Deal which randomises the order of list Deck, then in a loop 1-13 creates or overwrites a two-dimensional 
array Hand[0-3][0-12] by copying the value in the next entry in Deck.
Master routine to call both and print out the values in Hand.
Deck and Hand to be global.
