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 ...
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"] p_s=set(python_1) l_s=set(linux_1)print(p_s,l...

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 ...
set3 = set1.union(set2) print(set3) Try it Yourself » You can use the|operator instead of theunion()method, and you will get the same result. Example Use|to join two sets: set1 = {"a","b","c"} set2 = {1,2,3} ...
