整理Python关于读取多维数组的一行代码

Question

我有一句话：

board = [[int(cell) for cell in row] for row in [line.split() for line in boardFile]]

它读取如下文本文件：

0 0 0 0 0 0 0 0 0
0 0 0 1 0 0 0 0 0
0 1 0 1 0 0 0 0 0
0 0 1 1 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 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
0 0 0 0 0 0 0 0 0

并创建如下多维数组：

[[0, 0, 0, 0, 0, 0, 0, 0, 0],
 [0, 0, 0, 1, 0, 0, 0, 0, 0],
 [0, 1, 0, 1, 0, 0, 0, 0, 0],
 [0, 0, 1, 1, 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, 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],
 [0, 0, 0, 0, 0, 0, 0, 0, 0]]

但是，它看起来很不整洁，有人能改进它吗？你知道吗

Answer 1

board = [map(int, line.split()) for line in boardFile]

或者python3中的board = [list(map(int, line.split())) for line in boardFile]。你知道吗
