In set theory, the union (denoted by ∪) of a collection of sets is the set of all elements in the collection. It is one of the fundamental operations through which sets can be combined and related to each other. A nullary union refers to a union of zero (0) sets and it is by ...
And everyone consists of all of the males and all of the females. Python中集合并集的简写操作是垂直线。 The short hand operation for a set union in Python is a vertical line. 再次,如果我查看集合everyone的内容,我可以看到集合中的所有成员都在那里。 Again if I look at the contents of the ...

In this code, we convertlist1andlist2to sets usingset()function, find the intersection usingintersection()function, and then convert the resulting set back to a list usinglist()function. Union Theunionfunction returns a new set or list containing all the unique elements from two sets or list...
Return the union of sets as a new set 求2个集合的并集(就是把2个集合合并成一个集合,因为集合有去重特性,所以就是把2个集合合并成一个集合并去除重复的) python_1 = ["ggq","ytj","mr","mr","ggq"] linux_1= ["ggq","ytj","sb"] ...
of set B with no repetition of elements and is named as union of set A and B. 用法: set1.union(set2, set3, set4….) In parameters, any number of sets can be given 返回值: The union() function returns a set, which has the union of all sets(set1, set2, set3…) with set...
