我们可以随意选， 但随意选的后果是不能让set最优，所以可以从侧面反映出如果有【规则】的选择，可能达...
6、set.discard():如果它是一个成员,从集合中移除一个元素。如果元素不是成员,则什么都不做。 7、set.intersection():将两个集合的交集作为一个新集合返回。 8、set.intersection_update():用自己和另一个的交集更新一个集合。 9、set.isdisjoint():如果两个集合交集为空,返回True。 10、set.issubset():报...
intersection_update() 方法:用于就地更新集合为交集。 &= 运算符:用于原地更新集合为交集。 set1 = {1,2,3} set2 = {3,4,5}# 使用 & 运算符计算交集intersection_set_operator = set1 & set2print(intersection_set_operator)# 输出: {3}# 使用 intersection() 方法计算交集intersection_set_method =...
The syntax of the intersection function is given below: set A.intersection(set B, set C, set D, …) Here, the intersection method takes a parameter as the set variable for which the common element is found. It returns as the new set containing the common elements of all the sets(set...
y = set() x.intersection_update(y) print(x) Program Output set() Conclusion In thisPython Tutorial, we learned about Python set method intersection_update(). We have gone through the syntax of intersection_update() method, and its usage with example programs....
