sorted_ordered_list = remove_duplicates_and_order_sort(original_list) print(sorted_ordered_list) # 输出: [1, 2, 3, 4] 三、利用pandas库进行大数据集的去重排序 对于大型数据集,pandas库提供了强大的数据处理功能,包括去重和排序。在pandas中,可以使用DataFrame或Series的drop_duplicates()方法进行去重,然后...

To remove duplicates from a Python list while preserving order, create a dictionary from the list and then extract its keys as a new list: list(dict.fromkeys(my_list)).
如果需要保持元素顺序,可以使用dict.fromkeys()方法,如下:def remove_duplicates_ordered(original_list)...
https://leetcode.cn/problems/remove-duplicates-from-sorted-list/思路:跟数组这个完全一样!!! # Definition for singly-linked list. # class ListNode: # def __init__(self, val=0, next=None): # self.val = val # self.next = next
list有一些非常有用的方法,比如append,extend,insert,remove,pop,index,count,sort,reverse,copy等。 举个例子: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 >>> fruits = ['orange', 'apple', 'pear', 'banana', 'kiwi', 'apple', 'banana'] >>> fruits.count('apple') 2 >>> fruits.cou...
