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) ...
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
As you can see, thelanguages2list is added as a single element at the end oflanguages1, creating a nested list. Now,languages1contains three elements, where the last element is the entirelanguages2list. Similarly, you can also append multiple lists to another list. Using appending a list c...

Lists are sequences that can hold different data types and Python objects, so you can use .append() to add any object to a given list. In this example, you first add an integer number, then a string, and finally a floating-point number. However, you can also add another list, a di...
深入链表(most on lists) The list data type has some more methods. Here are all of the methods of list objects: list.append(x) 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; equival...
# Example 1: Convert the list to a set # Using set() myset = set(lists) # Example 2: Convert list to set # Using for loop myset = set() for item in lists: myset.add(item) # Example 3: Convert list to set # Using set comprehension ...
