如何在Python的子列表中添加元素?

问题描述：

考虑列表内的列表

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

subelement1可以通过索引[2] [0]

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insert函数，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)

让我说我想在 [2]，[0] 处插入"subelement0" .这就是列表:

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

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

答

尝试将元素插入到子列表中，如下所示:

Try to insert element to sublist as below:

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