如何打印格式化为网格的二维列表？

目前，我已经编写了这段代码

def grid_maker(h,w):
    grid = [[["-"] for i in range(w)] for i in range(h)]
    grid[0][0] = ["o"]
    print grid

>>>grid_maker(3,5) => [[['o'], ['-'], ['-'], ['-'], ['-']], [['-'], ['-'], ['-'], ['-'], ['-']], [['-'], ['-'], ['-'], ['-'], ['-']]] 

我想创建另一个函数，它将接受生成的二维数组并将其打印出来，使其采用以下格式：

o----
-----
----- 

但是，我不确定从哪里开始。

如果你想“漂亮”地打印你的网格，每个子列表都在自己的行上，你可以使用pprint:

>>> grid=[[['o'], ['-'], ['-'], ['-'], ['-']], [['-'], ['-'], ['-'], ['-'], ['-']], [['-'], ['-'], ['-'], ['-'], ['-']]]

>>> from pprint import pprint
>>> pprint(grid)

[[['o'], ['-'], ['-'], ['-'], ['-']],
 [['-'], ['-'], ['-'], ['-'], ['-']],
 [['-'], ['-'], ['-'], ['-'], ['-']]]

正如您所定义的那样，它仍然会将每个元素显示为列表，如果您想将它们显示为字符串，则必须使用 m.wasowski 建议的连接。
