是否有更好(和更短)的方式来创建像数组一样的棋盘.董事会的要求是：

>板子可以是不同的尺寸(在我的例子中它是3×3)

>板的左下方应始终为黑色

>黑色方块用“B”表示,白色方块用“W”表示

我有的代码：

def isEven(number):

return number % 2 == 0

board = [["B" for x in range(3)] for x in range(3)]

if isEven(len(board)):

for rowIndex, row in enumerate(board):

if isEven(rowIndex + 1):

for squareIndex, square in enumerate(row):

if isEven(squareIndex + 1):

board[rowIndex][squareIndex] = "W"

else:

for squareIndex, square in enumerate(row):

if not isEven(squareIndex + 1):

board[rowIndex][squareIndex] = "W"

else:

for rowIndex, row in enumerate(board):

if not isEven(rowIndex + 1):

for squareIndex, square in enumerate(row):

if isEven(squareIndex + 1):

board[rowIndex][squareIndex] = "W"

else:

for squareIndex, square in enumerate(row):

if not isEven(squareIndex + 1):

board[rowIndex][squareIndex] = "W"

for row in board:

print row

输出：

['B', 'W', 'B']

['W', 'B', 'W']

['B', 'W', 'B']
