方法一:使用集合(set)来去除重复元素 Python中的集合(set)是一种无序且不重复的数据类型,我们可以利用这一特性来去除列表中的重复元素。 # 定义一个包含重复元素的列表my_list=[1,2,2,3,4,4,5]# 使用集合(set)去除重复元素unique_elements=list(set(my_list))print(unique_elements) 1. 2. 3. 4. 5...
通过比较集合和列表的长度,我们可以确定是否存在重复元素。 以下是使用这种方法的Python代码示例: deffind_duplicates_2(my_list):unique_elements=set(my_list)iflen(unique_elements)<len(my_list):returnlist(set([xforxinmy_listifmy_list.count(x)>1]))else:return[]my_list=[1,2,3,1,4,5,1]resul...
Build an unordered collection of unique elements. 集合内置方法: defadd(self, *args, **kwargs):"""Add an element to a set. This has no effect if the element is already present."""pass给集合添加一个元素,当元素已存在时,集合不变。defclear(self, *args, **kwargs):"""Remove all element...
(You will see a Python data type that is not ordered in the next tutorial on dictionaries.)Lists that have the same elements in a different order are not the same:>>> a = ['foo', 'bar', 'baz', 'qux'] >>> b = ['baz', 'qux', 'bar', 'foo'] >>> a == b False>>> ...
