```Python class UnorderedList: def __init__(self): self.head = None ``` __str__方法的实现方式是:将链表中的节点从链首开始遍历,每个节点的数据成员(data)append进一个list,最后返回str(list)。 ```Python def __str__(self): print_list = [] current = self.head while current is not No...
有序和无序仅仅指节点所包含的数据成员的大小排列顺序,有序指各个节点按照节点数据成员的大小顺序排序,从大到小或从小到大。无序则可以任意排列。 链表节点实现 实现方式完全同单向无序列表,这里不再过多介绍,感兴趣的可以看Python实现单向无序链表(Singly linked list)关于节点的实现方式。 链表实现 链表的实现中,...

First, we have seen how to create Python Singly LinkedList using SLL() and then we used the insert() method to put elements into it. The first node of the linked list is deleted using the delete_f() method and the last node of the linked list is deleted using the delete_l() ...
