Question

board = []
for integer in range(1,6):
    board.append("O")
print(str(board)*5)

That’s my code. My problem is that the output doesn’t come out as a 5×5 grid. Am I missing another for loop? (I know I could probably use list comprehensions as well).

thank you.

Answer 1

If you want a 5x5 grid, you could join the results …

'\n'.join([' '.join(board)]*5)

example:

>>> board = ['0']*5
>>> print '\n'.join([' '.join(board)]*5)
0 0 0 0 0
0 0 0 0 0
0 0 0 0 0
0 0 0 0 0
0 0 0 0 0

To get the output you’re looking for, you can do

>>> board = [['0'] for _ in range(5)]
>>> board
[['0'], ['0'], ['0'], ['0'], ['0']]
>>> print '\n'.join(str(board) for _ in range(5))
[['0'], ['0'], ['0'], ['0'], ['0']]
[['0'], ['0'], ['0'], ['0'], ['0']]
[['0'], ['0'], ['0'], ['0'], ['0']]
[['0'], ['0'], ['0'], ['0'], ['0']]
[['0'], ['0'], ['0'], ['0'], ['0']]
