Hey, I've found a pretty understandable and easy editable solution to your problem! I've added a lot of comments and annotations so you can understand how it's all working!
PS: I coded this in Python3 and yes the formatting looks awful but copy+paste it in an editor and everything will look fine :)
--------------------------------------------------------------------------------------------------
# Import the random module in order to shuffle the deck randomly every time
from random import shuffle
# Create a 'shuffle_deck' function
def shuffle_deck():
# (NOT NECESSARY) Define what is the function doing
"""Returns the order of a shuffled deck of cards in a list."""
### If we consider a deck of 52 cards, it implies that there's 13 cards per family. ###
# Create a list / array containing all the four card families of the 52 deck of cards
cards = [
'SAce', 'S2', 'S3', 'S4', 'S5', 'S6', 'S7', 'S8', 'S9', 'SJack', 'SQueen', 'SKing', # Spades family
'HAce', 'H2', 'H3', 'H4', 'H5', 'H6', 'H7', 'H8', 'H9', 'HJack', 'HQueen', 'HKing', # Hearts family
'CAce', 'C2', 'C3', 'C4', 'C5', 'C6', 'C7', 'C8', 'C9', 'CJack', 'CQueen', 'CKing', # Clubs family
'DAce', 'D2', 'D3', 'D4', 'D5', 'D6', 'D7', 'D8', 'D9', 'DJaDk', 'DQueen', 'DKing', # Diamonds family
]
shuffle(cards)
# Return the shuffled deck as a list
return cards
# Test the 'shuffle_deck' function by printing the result
print(shuffle_deck())
