区别:remove()和discard()都是对set集合中的元素进行删除,不同的是,remove()方法删除不存在的元素时会报错,但是discard()方法不会报错 Symmetric_difference() 返回两个集合中不重复的元素集合(对称差集) 注意:会产生新的集合 symmetric_difference_update() 移除两个集合的相同元素,增加不同的元素(对称差集) 注...
1 # 对称差集:去掉两集合里面都有的,然后合并两个集合并去重 2 s1 = set('aaee1122') 3 s2 = {'1','2','1','4','2','5','7'} 4 print(s1 ^ s2) 5 print(s1.symmetric_difference(s2))9、练习1 # 校验密码里面是否包含数字、大写字母、小写字母和特殊符号 2 import string 3 num_set...

C {"15"} D {"12", "18"} 问题解析 1.symmetric_difference()方法的功能是:用于返回所给的两个集合中不重复的元素,即两个集合中都存在的元素不会返回。 2.本题考查symmetric_difference()方法,集合a包含12、15、18三个元素,集合b包含16、15、22三个元素,两个集合都包含15,所以结果为:{"12", "18"...
The only difference is that the decorator will receive a class and not a function as an argument. In fact, all the decorators that you saw above will work as class decorators. When you’re using them on a class instead of a function, their effect might not be what you want. In the ...
