intersection(set(Y))) Output:set() 4) Python Intersection of Multiple SetsThe & operator or the intersection() method in Python can be used to execute an intersection of multiple sets. The intersection() method is employed to perform an intersection of many sets, whereas the & operator is ...
Theintersection()method returns a set that contains the similarity between two or more sets. Meaning: The returned set contains only items that exist in both sets, or in all sets if the comparison is done with more than two sets.
set1={1,2,3}set2={3,4,5}union_set=set1|set2print(union_set)# 输出: {1, 2, 3, 4, 5} 5.2 交集(Intersection) **&**:找出两个集合共有的元素,形成新的集合。 intersection_set=set1&set2print(intersection_set)# 输出: {3} 5.3 差集(Difference) **-**:从一个集合中移除另一个集合...

数学上,把set称作由不同的元素组成的集合,集合(set)的成员通常被称作集合元素(set elements)。 Python把这个概念引入到它的集合类型对象里。集合对象是一组无序排列的可哈希的值,集合成员可以做字典中的键。数学集合转为Python的集合对象很有效,集合关系测试和union、intersection等操作符在Python里也同样如我们所预想...
>>> print(num_set) {1, 2, 3, 4, 5} >>> discard() function: >>> num_set = set([0, 1, 2, 3, 4, 5]) >>> num_set.discard(3) >>> print(num_set) {0, 1, 2, 4, 5} >>> Intersection of sets: In mathematics, the intersection A ∩ B of two sets A and B is ...
my_set2 = {'apple', 'banana', 'orange'} s1=set('cheney') s2=set(['a','b','c']) s1&s2 # 等同于s1.intersection(s2) 2.并集 # 并集 | s1=set('cheney') s2=set(['a','b','c']) s1|s2 # s1.union(s2) 3.差集
Python sets are especially useful for keeping track of distinct objects and doing mathematical set operations like unions, intersection
A set itself may be modified, but the elements contained in the set must be of an immutable type.集合本身是可以修改的,但集合中的元素本身不可修改。此说可通过“集合元素相当于字典的键”来理解 Let’s see what all that means, and how you can work with sets in Python. ...
set3 = set1.intersection(set2)print(set3) Try it Yourself » You can use the & operator instead of the intersection() method, and you will get the same result.Example Use & to join two sets: set1 = {"apple", "banana", "cherry"}set2 = {"google", "microsoft", "apple"} se...
