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
Python Set Union We can combine two or more sets together and get a combined set as a result. To do this we usepython set unionmethod. We can also use“|” operatorto get the same result inPython Programming. To learn this lesson of python, we will give different examples below. You ...
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'} y = {'apple', 'banana', 'mango', 'guava'} result = x.union(y) print(result) Program Output {'apple', 'banana', ...
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 set1. It returns a copy of set1 only if no parameter is passed. 以下是上述方法的Python3实现...
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 ...
