在C中，我们会这样定义和初始化这样一个三维数组：
 int Table[12][12][12];
 for(i=0;i<12;i++)
        for(j=0;j<12;j++)
            for(k=0;k<12;k++)
                Table[i][j][k]=1;
那我在Python中用如下方式是否最简单：
        Table = []
        i = 0
        while i < 12 :
            j = 0
            Table.append([])
            while j < 12 :
                k = 0
                Table[i].append([])
                while k < 12 :
                    Table[i][j].append(1)
                    k+=1
                j+=1
            i+=1
我想这个方法还是比较繁杂，不知道各位有没有更简单一点的方法？

Table = [[[[1] * 12] for x in range(12)] for x in range(12)]

不好意思，写错了，应该是：
Table = [ [ [1] * 12 for x in range(12) ] for x in range(12) ]

这个构造出来的不是三维数组，修改其中一个元素就会导致其他元素发生变化。

例如：

.>>> x = [[[1]*3]*3]*3
.>>> x
[[[1, 1, 1], [1, 1, 1], [1, 1, 1]], [[1, 1, 1], [1, 1, 1], [1, 1, 1]], [[1, 
1, 1], [1, 1, 1], [1, 1, 1]]]
.>>> x[1][1][1] = 2
.>>> x
[[[1, 2, 1], [1, 2, 1], [1, 2, 1]], [[1, 2, 1], [1, 2, 1], [1, 2, 1]], [[1, 
2, 1], [1, 2, 1], [1, 2, 1]]]
