使用集合的交集函数。a_set.intersection（b_set）如果至少有一个元素是公共的，则返回正整数，否则返回0。因此，我们在set_a中插入a，在set_b中插入b，然后检查a_set.intersection（b_set），并根据值返回。def common_member(a, b):a_set = set(a)b_set = set(b)if len(a_set.intersection(b_set)...
If two lists have intersection, then their last nodes must be the same one. So when pA/pB reaches the end of a list, record the last element of A/B respectively. If the two last elements are not the same one, then the two lists have no intersections. Analysis written by@stellari....
``intersect_set = set1.intersection(set2)``语句实现了取集合交集的操作。
#Intersection of two list (Get the elements that both have) list(set(list1) & set(list2)) 获得后者相对于前者的补集 #Difference of two list (Get the elements that the former have, the latter don't) list(set(list1) - set(list2)) 获得两个list的差集 #Symmetric difference of two list...
