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 can also check t...
Union of three set shown in green color Example 2: Set Union Using the | Operator You can also find the union of sets using the | operator. A = {'a', 'c', 'd'} B = {'c', 'd', 2 } C = {1, 2, 3} print('A U B =', A| B) print('B U C =', B | C) ...
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...
