Python 创建列表索引超出范围的矩阵？

我正在尝试创建一个3x10x10矩阵，我觉得我做得不错。我试图让

GridSet

函数为我设置所有值，我在第7行得到一个错误，即“列表索引超出范围”。我不明白为什么我会出错

如果有更好的方法来创建矩阵，而不需要大量的方括号（没有模块，我听说过NumPy，但我想赤裸裸地这样做），那就很好了

我运行的是2.6.x，不确定是哪个版本。任何帮助都将不胜感激

import random

def GridSet(fullGrid):
    letters = ['A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J']
    for j in range(10):
        for i in range(10):
            fullGrid[j][i][0].append(letters[j]+str(i+1))
            fullGrid[j][i][1].append(random.randrange(100)+1)
            fullGrid[j][i][2].append(0)


#main
fullGrid = [[[],[],[],[],[],[],[],[],[],[]],[[],[],[],[],[],[],[],[],[],[]],[[],[],[],        [],[],[],[],[],[],[]],[[],[],[],[],[],[],[],[],[],[]],[[],[],[],[],[],[],[],[],[],[]],[[],[],[],[],[],[],[],[],[],[]],[[],[],[],[],[],[],[],[],[],[]],[[],[],[],[],[],[],[],[],[],[]],[[],[],[],[],[],[],[],[],[],[]],[[],[],[],[],[],[],[],[],[],[]]]
filledGrid = GridSet(fullGrid)
print filledGrid

有点困惑。这就是你想要达到的目标吗

import random

def GridSet():
    fullGrid = []
    letters = ['A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J']

    for j in range(10):
        collect = []
        for i in range(10):
            collect_sub = []
            collect_sub.append([letters[j] + repr(i+1), random.randrange(100)+1, 0])
            collect.append(collect_sub)
        fullGrid.append(collect)

    return fullGrid

filledGrid = GridSet()

import pprint
pprint.pprint(filledGrid)

输出

如果缩进太深，只需删除

fullGrid

的附加，而不会破坏其余完整性。

以下嵌套列表应创建原始列表：

In [13]: [[[None for i in range(3)] for j in range(10)] for k in range(10)]
Out[13]: 
[[[None, None, None],
  [None, None, None],
  [None, None, None],
  [None, None, None],
  [None, None, None],
  [None, None, None],
  [None, None, None],
  [None, None, None],
  [None, None, None],
  [None, None, None]],
 [[None, None, None],
  [None, None, None],
  [None, None, None],
  ... etc

尽管您可以创建整个内容，而不是先创建列表，然后填充列表：

In [23]: l = [[[letters[j]+str(i+1), random.randrange(100)+1, 0] for i in range(10)]for j in range(10)]
In [24]: pprint(l)
[[['a1', 82, 0],
  ['a2', 77, 0],
  ['a3', 64, 0],
  ['a4', 34, 0],
  ['a5', 95, 0],
  ['a6', 69, 0],
  ['a7', 4, 0],
  ['a8', 72, 0],
  ['a9', 83, 0],
  ['a10', 100, 0]],
 [['b1', 19, 0],
  ['b2', 59, 0],
  ['b3', 15, 0],
   ...

你需要一个更好的描述，但我只想写一行字来解决我认为你在寻找的问题

import random

def GridSet(letters):
    letRange = range(len(letters))
    return [ [[letter for letter in letters] for v in letRange], 
             [[random.randrange(100)+1 for i in letRange] for v in letRange], 
             [[0 for i in letRange] for v in letRange] ]

grid = GridSet(["A", "B", "C", "D", "E", "F", "G", "H", "I", "J"])

# len(grid):  3
# len(grid[0]):  10
# len(grid[0][0]):  10

您也可以使用python-v来查找您的python版本。@Joe原来这就是问题所在。但我想不出来。我使用的格式是[打开整个列表（x10）[打开第二个列表（x10）[打开第三个列表（x3）]]您如何定义fullGrid（位于底部）存在问题。如果您让它在循环之前打印fullGrid[0][0][0]，会发生什么情况？您还将得到超出范围的列表索引。您的列表现在定义为2x2，而不是3x3。我在

字母列表中看到了10（0,9）个字母。我看起来不对吗
