我正在尝试制作一个将二进制列表交错到数组中的函数。矩阵大小为 10 行 x 9 列，初始化为None. 这些位一次被送入矩阵，第一个输入位被送入 (0,0)。这些位被送入（前一行 + 7）模 10，当列满时，列向右移动，第 0 列填充下一组位。但是，我遇到了列填充循环的问题。零列中的每一行都被设置为相同的值！

这是我到目前为止所拥有的：

>>> row = 0
>>> interleave_row = [None,None,None,None,None,None,None,None,None]
>>> interleave_matrix = [interleave_row,interleave_row,interleave_row,interleave_row,interleave_row,interleave_row,interleave_row,interleave_row,interleave_row,interleave_row]

这会产生一个矩阵，如下所示：

    [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, 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, None, None, None]]

>>> input = [0, 0, 1, 0, 0, 0, 0, 1, 1, 1, 1, 0, 1, 1, 1, 1, 0, 0, 1, 0, 1, 1, 1, 0, 0, 0, 0, 1, 1, 0, 1, 1, 1, 1, 1, 0, 1, 0, 1, 1, 0, 1, 1, 1, 0, 1, 0, 1, 0, 1, 1, 1, 1, 0, 0, 0, 1, 0, 1, 1, 1, 1, 0, 1, 0, 0, 0, 0, 1, 0, 1, 0, 0, 1, 0, 1, 1, 0, 0, 0, 0, 1, 0, 1, 1, 0, 0, 1, 0, 0]
>>> for i in range(0,10):
        interleave_matrix[row][0] = input[i]
        row = (row+7)%10

这产生：

    [1, None, None, None, None, None, None, None, None],
    [1, None, None, None, None, None, None, None, None],
    [1, None, None, None, None, None, None, None, None],
    [1, None, None, None, None, None, None, None, None],
    [1, None, None, None, None, None, None, None, None],
    [1, None, None, None, None, None, None, None, None],
    [1, None, None, None, None, None, None, None, None],
    [1, None, None, None, None, None, None, None, None],
    [1, None, None, None, None, None, None, None, None]]

它应该如下所示：

    [0, None, None, None, None, None, None, None, None],
    [1, None, None, None, None, None, None, None, None],
    [0, None, None, None, None, None, None, None, None],
    [0, None, None, None, None, None, None, None, None],
    [0, None, None, None, None, None, None, None, None],
    [0, None, None, None, None, None, None, None, None],
    [1, None, None, None, None, None, None, None, None],
    [1, None, None, None, None, None, None, None, None],
    [1, None, None, None, None, None, None, None, None]]

我有一个菜鸟时刻吗？我知道行增量工作正常，因为我自己循环了它。什么可能导致这种奇怪的行为？

编辑：我只是尝试循环遍历前四位（保证以 0 位结束），它没有将整行设置为该位，它只是将整行设置为 1。越来越奇怪了……

帕维尔发布的答案！

您的矩阵实际上包含对同一列的 N 个引用。因此，当您修改一列中的值时，该值也会在所有其他列中被修改。考虑以另一种方式创建矩阵以制作独立列：stackoverflow.com/q/2397141/6131611 stackoverflow.com/q/6667201/6131611

这绝对是一个菜鸟时刻，但我必须从中学习！谢谢！
