将列表插入包含多个列表的列表中

Question

用于知识目的

Input:

    [[[[[], [], []]], ['trynda'], [[[], [], []]]], ['cait'], [[[[], [], []]], ['veigar'], [[[], [], []]]]]

Output:

    [[[[[], [x], []]], ['trynda'], [[[], [], []]]], ['cait'], [[[[], [], []]], ['veigar'], [[[], [], []]]]]

如何将x添加到列表列表的第二个列表中？

Answer 1

只需使用嵌套索引（适用于嵌套列表）：

original_list[0][0][0][1].append(x)  # 2nd of 1st of 1st of 1st.

假设x是一个变量。否则，请使用字符串'x'。

演示：

>>> original_list = [[[[[], [], []]], ['trynda'], [[[], [], []]]], ['cait'], [[[[], [], []]], ['veigar'], [[[], [], []]]]]
>>> original_list[0][0][0][1].append('x')
>>> original_list
[[[[[], ['x'], []]], ['trynda'], [[[], [], []]]], ['cait'], [[[[], [], []]], ['veigar'], [[[], [], []]]]]
          ^

Answer 2

my_list[0][0][0][1].append(x)

假设x包含值。如果是字符串，您需要'x'。
