题目描述如下：

T83 删除排序链表中的重复元素

解题思路：

每一个检查一下，一直到链表最后就好啦

代码如下：

# Definition for singly-linked list.
# class ListNode:
#     def __init__(self, val=0, next=None):
#         self.val = val
#         self.next = next
class Solution:
   def deleteDuplicates(self, head: ListNode) -> ListNode:
       p = head
       p_aft = head
       if p is None or p.next is None:
           return p
       else:
           p_aft == p.next
       while p_aft != None:
           if p.val == p_aft.val:
               p.next = p_aft.next
               p_aft = p_aft.next
           else:
               p = p.next
               p_aft = p_aft.next
       
       return head

结果如下：
