Explanation / Answer
Actually in the first while loop which is started from 8th line has an error and the error is that at the end of the loop you have reinitialised the value of i to 0. which makes an infinite loop and hence the code is not showing any output. I have rectified the code and you can run this code. this is working.
dCardNames = ['2','3','4','5','6','7','8','9','10','J','Q','K','A']
dCardValues = ['2','3','4','5','6','7','8','9','10','11','12','13','14']
dSuits = ["Clubs","Spades","Diamonds","Hearts"]
# Build a two dimensional deck with Cards suits and values.
aCards = [['' for i in range(52)] for j in range(3)]
i = 0
n = 0
while (i < 13):
aCards[0][i] = dCardNames[i]
aCards[0][i + 13] = dCardNames[i]
aCards[0][i + 26] = dCardNames[i]
aCards[0][i + 39] = dCardNames[i]
aCards[1][i] = dSuits[0]
aCards[1][i + 13] = dSuits[1]
aCards[1][i + 26] = dSuits[2]
aCards[1][i + 39] = dSuits[3]
aCards[2][i] = dCardValues[i]
aCards[2][i + 13] = dCardValues[i]
aCards[2][i + 26] = dCardValues[i]
aCards[2][i + 39] = dCardValues[i]
i = i + 1
while (i < 52):
print (aCards[0][i], " ", aCards[1][i], " ", aCards[2][i])
