Python - 是否可以将insert（）插入到列表中的列表中？

Question

In Python is it possible to insert a value inside a list that's inside a list?

for example:

    List = [['Name',[1, 4, 6]],
    ['Another Name', [1,2,5]]]

I've tried to use:

    List.insert([0][1], 'another value')

but it doesn't like that, is there another way to manipulate lists inside lists?

Answer 1

Definitely possible:

>>> List = [['Name',[1, 4, 6]],
...     ['Another Name', [1,2,5]]]
>>> List[0].insert(1,"Another Value")
>>> List
[['Name', 'Another Value', [1, 4, 6]], ['Another Name', [1, 2, 5]]]

You just need to subscript the "outer" list to get a reference to the "inner" list that you want to insert into.

We could break the above code into the following steps:

inner = List[0]
inner.insert(1,'Another Value')

If that makes it more clear to you what I actually did there ...
