Python 集合描述union() 方法返回两个集合的并集,即包含了所有集合的元素,重复的元素只会出现一次。语法union() 方法语法:set.union(set1, set2...)参数set1 -- 必需,合并的目标集合 set2 -- 可选,其他要合并的集合,可以多个,多个使用逗号 , 隔开。

Python的集合(set)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union(联合), intersection(交), difference(差)和sysmmetric difference(对称差集)等数学运算。…
{'Fili', 'Dwalin', 'Balin', 'Gimli', 'Bofur', 'Thorin', 'Kili'} You can also checkPython Set Remove Methods Now, let’s use “|” operator to get the same result. Here, we will use this operator between the sets in print function. dwarves1 = {"Thorin", "Balin", "Dwalin"} ...
set.union(set1, set2...) where The method returns a set with elements from all the sets. Examples 1. Union of two sets In the following program, we will take two sets:x,y; and find their union. Python Program </> Copy x = {'apple', 'banana', 'cherry'} ...
Write a function to get the sum of union of two sets. Return the sum of all elements in the union set. For example, for inputs {1, 2, 3, 4} and {2, 3, 4, 5}, the output should be 15. 1 2 def get_union_sum(set1,set2): Check Code Previous Tutorial: Python Set symm...

python的set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union(联合), intersection(交), difference(差)和sysmmetric difference(对称差集)等数学运算。 sets 支持 x in set的bool运算判别x是否在集合内, len(set)集合的长度,和 for x in set对集合内数据的...
In this code, we convertlist1andlist2to sets usingset()function, find the union usingunion()function, and then convert the resulting set back to a list usinglist()function. Conclusion In this article, we discussed theintersectionandunionfunctions in Python. These functions are useful when we ...
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 set1. It returns a copy of set1 only if no parameter is passed. 以下是上述方法的Python3实现: ...
