Python set()函数 Python 内置函数 描述 set()函数创建一个无序不重复元素集,可进行关系测试,删除重复

pythonset和其他语言类似,是一个无序不重复元素集,基本功能包括关系测试和消除重复元素.集合对象还支持

set的内容 diffrence_update set1.difference_update(x)先找出set1 和 x不同的元素,不同元素不包含 x里面

a=set('python') a.add('why') print(a) b=set('python') b.update('why') print(b) {'n','p','y','h','o',

list1=[1,2,3,4]s=set(list1)print(s)s.add(4)s.add(5)print(s)输出:set([1,2,3,4])set([1,2,3,4,5])

python set类是在python的sets 模块 中,大家现在使用的python2.3中,不需要导入sets模块可以直接创建集合

Python中 集合set 是基本数据类型的一种,它有可变集合(set)和不可变集合(frozenset)两种。创建集合set
