The list data type has some more methods. Here are all of the methods of list objects:除了第前面的，列表还有更多的方法，下面就是列表对象的所有方法：list.append(x)Add an item to the end of the list. Equivalent to a[len(a):] = [x].本方法是添加一个元素到列表末，相当于a[len(a):]...
Add an item to the end of the list; equivalent toa[len(a):]=[x]. list.extend(L) 添加一组数据到list 的末尾 Extend the list by appending all the items in the given list; equivalent toa[len(a):]=L. list.insert(i,x) 在指定位置插入一个数据 Insert an item at a given position. T...
Add an item to the end of the list; equivalent toa[len(a):]=[x]. list.extend(L)#将两个 list 中的元素合并到一起 Extend the list by appending all the items in the given list; equivalent toa[len(a):]=L. list.insert(i,x)#将元素插入到指定的位置(位置为索引为 i 的元素的前面一个...
List items are indexed, the first item has index[0], the second item has index[1]etc. Ordered When we say that lists are ordered, it means that the items have a defined order, and that order will not change. If you add new items to a list, the new items will be placed at the...
