from collections import Countermy_list = [1, 2, 2, 3, 4, 4, 5]count = Counter(my_list)unique_list = [item for item, count in count.items()]5.使用set()和add()方法：你可以创建一个空集合，然后逐个添加元素，集合会自动去重。codemy_list = [1, 2, 2, 3, 4, 4, 5]unique_set ...
方法一:使用Counter类(推荐) Python的collections模块中的Counter类可以方便地统计List中某元素的个数。首先,你需要从collections模块导入Counter类,然后创建一个Counter对象,将List作为参数传递给Counter构造函数。最后,使用Counter对象的get()方法来获取指定元素的个数。这种方法简洁且高效,非常适合快速统计元素个数。 以下...

对一个列表,比如[1,2,2,2,2,3,3,3,4,4,4,4],现在我们需要统计这个列表里的重复项,并且重复了几次也要统计出来。 方法1 mylist = [1,2,2,2,2,3,3,3,4,4,4,4] myset = set(mylist) #myset是另外一个列表,里面的内容是mylist里面的无重复 项 for item in myset: print("the %d has...
