如何将元素添加到 Python 中的子列表?

考虑列表中的列表

list1 = ["element1","element2",["subelement1","subelement2"]]

子元素1可以通过索引[2][0]访问

subelement1 can be accessed by index [2][0]

print (list1[2][0])

但是如果只能将两个参数传递给插入函数，我该如何在 [2][x] 位置插入元素.

But how can I insert elements at [2][x] position if only two parameters can be passed to insert function.

list.insert(index, element)

假设我想在 [2],[0] 处插入 "subelement0".这使得列表:

Lets say i want to insert "subelement0" at [2],[0]. That makes the list :

list1 = ["element1","element2",["subelement0","subelement1","subelement2"]]

尝试如下插入元素到子列表:

Try to insert element to sublist as below:

list1[2].insert(0, 'subelement0') 
print(list1)
#  ['element1', 'element2', ['subelement0', 'subelement1', 'subelement2']]
