Thedelfunction in python is used to delete objects. And since in python everything is an object so we can delete any list or part of the list with the help ofdelkeyword. To delete the last element from the list we can just use the negative index,e.g-2and it will remove the last ...
The pop function removes and returns the element at the given index. If the index is not explicitly defined, it defaults to the last. The function raises IndexError if list is empty or the index is out of range. main.py #!/usr/bin/python words = ["sky", "cup", "new", "war",...

[Leetcode][python]Remove Element/移除元素 题目大意 去掉数组中等于elem的元素,返回新的数组长度,数组中的元素不必保持原来的顺序。 解题思路 双指针 使用头尾指针,头指针碰到elem时,与尾指针指向的元素交换,将elem都换到数组的末尾去。 代码 判断与指定目标相同...
