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)).
Python'sdictclass has afromkeysclass methodwhich accepts aniterableand makes a new dictionary where the keys are the items from the given iterable. Since dictionaries can't have duplicate keys, this also de-duplicates the given items! Dictionaries also maintain the order of their items (as of ...
Remove Duplicates from List Write a Python program to remove duplicates from a list. Visual Presentation: Sample Solution: Python Code: # Define a list 'a' with some duplicate and unique elementsa=[10,20,30,20,10,50,60,40,80,50,40]# Create an empty set to store duplicate items and ...

my_list = remove_duplicates(my_list) print(my_list) 在这个代码片段中,使用递归函数来遍历列表并去除重复元素。该函数从末尾开始构建结果列表,确保每个元素只出现一次。 九、使用双指针技术 双指针技术常用于数组和链表的操作中,也可以用来去除列表中的重复元素。这种方法特别适合处理有序列表。
unique_list.append(item) seen.add(item) return unique_list 示例 my_list = [ 1, 2, 3, 1, 2, 3, 4, 5] print(remove_duplicates(my_list)) 优点:可以保持列表的顺序。 缺点:比直接使用集合略微复杂一些。 三、使用列表推导式 列表推导式是一种简洁的方式,可以在保持顺序的情况下去除重复元素。
