To insert an element in ArrayList at a specific position, useArrayList.add(index, element)function whereindex(= i-1) specifies ithposition and theelementis the one that is inserted. When theelementis inserted,
Insert a new element at a specific index in the given linked list. The index is 0 based, and if the index is out of the list's scope, you do not need to do anything. Examples: 1 -> 2 -> 3 -> null, insert 4 at index 3, --> 1 -> 2 -> 3 -> 4 -> null 1 -> 2 ...

enumerate()与zip():前者是输出列表的index和元素值; 后者等长的两个列表对应为的元素组合成一个元组,生成一个元组列表。 sum()和reduce():对数字列表进行求和。 list()与tuple()接受可迭代对象作为参数,并通过浅拷贝数据来创建一个新的列表或元组。

The index must be a value greater than or equal to0and less than or equal to the current size of the vector. (If the index is equal to the current size of the vector, the new element is appended to the Vector.) This method is identical in functionality to the#add(int, Object) add...
