所以我正在尝试创建一个基于文本的游戏，有人建议我将地图数据存储为多维数组多维数组。在我看来，这将是非常困难的，但我不得不问，因为我自己无法弄清楚。如果这个问题太模糊，请告诉我应该更具体的内容。

多维数组只不过是一个数组，其元素映射到另一个数组，通常其中每个“子数组”的大小都相等（但不严格）。
inner = [ "" ] * 10
outer = [ [].extend(inner) for x in inner ]
这将为您创建一个 10 x 10 元素的方形多维数组。
您可以通过以下方式访问这些元素：
outer[outer_index][inner_index]
只需在网格上可视化外部和内部以及索引，外部遍历 x 轴，内部遍历 y 轴。上面的数组看起来有点像这样：
"" "" "" "" "" "" "" "" "" "" 0
"" "" "" "" "" "" "" "" "" "" 1
"" "" "" "" "" "" "" "" "" "" 2
"" "" "" "" "" "" "" "" "" "" 3
"" "" "" "" "" "" "" "" "" "" 4 (inner)
"" "" "" "" "" "" "" "" "" "" 5
"" "" "" "" "" "" "" "" "" "" 6
"" "" "" "" "" "" "" "" "" "" 7
"" "" "" "" "" "" "" "" "" "" 8
"" "" "" "" "" "" "" "" "" "" 9
0 1 2 3 4 5 6 7 8 9
(outer)
如果我在元素 6 和 8 处更新 outer 的值，网格将会改变：
outer[6][8] = "X" # marks the spot
"" "" "" "" "" "" "" "" "" "" 0
"" "" "" "" "" "" "" "" "" "" 1
"" "" "" "" "" "" "" "" "" "" 2
"" "" "" "" "" "" "" "" "" "" 3
"" "" "" "" "" "" "" "" "" "" 4 (inner)
"" "" "" "" "" "" "" "" "" "" 5
"" "" "" "" "" "" "" "" "" "" 6
"" "" "" "" "" "" "" "" "" "" 7
"" "" "" "" "" "" "X" "" "" "" 8
"" "" "" "" "" "" "" "" "" "" 9
0 1 2 3 4 5 6 7 8 9
(outer)
希望这会有所帮助。

手动创建多维列表：
world_map = [['*', '*', '*', '*'],
['*', ' ', 'i', '*'],
['*', ' ', ' ', '*'],
['*', '*', '*', '*']]
* 是一面墙，i 可能是玩家。
要遍历这个世界地图，请使用两个 for 循环：
for row in world_map:
for column in row:
print(column, end="")
print()
这将打印世界地图。
如果您需要向左移动播放器，您可以执行以下操作：
for row in world_map:
for i, column in enumerate(row):
if column == "i":
if i > 0 and row[i - 1] == ' ':
row[i - 1] = 'i'
row[i] = ' '
如果您知道元素的位置，也可以直接使用world_map[row][column] 访问元素。
您将不得不自己完成其余的工作。 此外，这可能不是最好的方法，您应该使用播放器类等，但这对初学者来说很好:)
