it can remove the first item from the ending of the list. In this example, I will pass the -3 index into the pop() method, and remove the third element from the end of the list, which is'Pandas'. # Use negative

The Python pop() method is a built-in method in Python that allows you to remove and return an item from the end of a list. It modifies the original list by removing the last element, and it returns the removed element.
# using pop() to delete element at pos 2 # deletes 3 lis.pop(2) # displaying list after popping print("List elements after popping are : ",end="") foriinrange(0,len(lis)): print(lis[i],end=" ") 输出: Listelements after deleting are:2138 ...
First, we define a list of "fruits" in the code above, which consists of four elements. The pop Function is then used on this list without an index point being specified. This retrieves the last element (the word "mango") from the list after removing it. Our ‘last_fruit’ variable ...
下面是一个使用 Python 的 redis-py 库进行 push 和 pop 操作的示例: importredis# 连接到 Redis 服务器r=redis.Redis(host='localhost',port=6379,db=0)# 向列表中添加元素r.lpush('mylist','hello')r.rpush('mylist','world')# 从列表中移除元素first_element=r.lpop('mylist')last_element=r.rpo...
