The extend() method does not have to append lists, you can add any iterable object (tuples, sets, dictionaries etc.).Example Add elements of a tuple to a list: thislist = ["apple", "banana", "cherry"] thistuple = ("kiwi", "orange") thislist.extend(thistuple) print(thislist) ...
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...
Add an item to the end of the list; equivalent toa[len(a):]=[x]. list.extend(L) Extend the list by appending all the items in the given list; equivalent toa[len(a):]=L. list.insert(i,x) Insert an item at a given position. The first argument is the index of the element bef...
Python 列表(List) 序列是Python中最基本的数据结构。序列中的每个元素都分配一个数字 - 它的位置,或索引,第一个索引是0,第二个索引是1,依此类推。 Python有6个序列的内置类型,但最常见的是列表和元组。 序列都可以进行的操作包括索引,切片,加,乘,检查成员。 此
Example 4: Append Multiple Complex Dictionaries to List using extend()In Example 4, first, I will import the deepcopy() function of the copy module to use in the implementation. Then I’ll create complex dictionaries containing lists and append the deep copies to the list using the extend(...
Add Elements to a Python List As mentioned earlier, lists are mutable and we can change items of a list. To add an item to the end of a list, we can use the list append() method. For example, fruits = ['apple', 'banana', 'orange'] print('Original List:', fruits) fruits.appen...
