试图得到一个好的格式输出，简单的Python

Question

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

这是我的密码。我的问题是输出并不是5x5网格。我是否错过了另一个for循环？（我知道我也可以使用列表理解）。你知道吗

谢谢你。你知道吗

Answer 1

如果你想要一个5x5网格，你可以join结果。。。你知道吗

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

示例：

>>> 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

为了得到你想要的结果，你可以

>>> 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']]

Answer 2

你错过了新词：

 print(('0'*6+'\n')*5)

Answer 3

In [22]: board = [['O'] * 5 for _ in range(5)]

In [23]: print('\n'.join(''.join(row) for row in board))
OOOOO
OOOOO
OOOOO
OOOOO
OOOOO
