lst = [1, 2, 2, 3, 3, 3]result = list(set(lst))print(result) # [1,2,3]
🐴用途——清理重复数据、统计唯一值、去重用户 ID、去重关键词a = {1,2,3,4}b = {3,4,5,6}print(a & b) # {3,4}
🐴用途——共同好友、共同爱好、共同购买记录、两份名单交集a = {1,2,3}b = {3,4,5}print(a - b) # {1,2}
a = {1,2,3}b = {3,4,5}print(a | b) # {1,2,3,4,5}
s = {"苹果", "香蕉", "橙子"}print("苹果" in s) # True
score = [80,90,80,90,100]print(len(set(score))) # 3种不同分数
