I don't know why this is not working


I don't understand why is this not making a 5x5 board. I imagine the first row of 5 ['O'] and the program that completes with other 4 ['O']s' to make the columns

board =  [['O'],['O'],['O'],['O'],['O']]
for i in range(0,5):


is it 3/19 if yes i did it this way

board = []
for x in range(5):
board.append(["O"] * 5)

print board

if not then can you tell what number it is
