Answer 1

一种简单的方法是：

ll=["Book","Glass","Book","Watch","Doll","Book"]
def a_list(l):
    for elem in l:
        if l.count(elem) > 1:
            print(elem)
        else:
            print(elem, "unique")

a_list(ll)

这将提供所需的输出

Answer 2

您可以简单地使用collections.Counter来检测计数不超过1的唯一项目。

from collections import Counter

lst=["Book","Glass","Book","Watch","Doll","Book"]

def a_list(items):
    counts = Counter(items)

    for item in items:
        if counts[item] > 1:
            print(item)
        else:
            print(f"{item} unique")

a_list(lst)

输出：

Book
Glass unique
Book
Watch unique
Doll unique
Book
