def get_dif_key_list(): list1 = [1, 2, 3] list2 = [2, 3, 4] result = [] s1 = set(list1) s2 = set(list2) #以list1為主，list2中缺少的 [1] s = s1.difference(s2) print(s) #s1 s2中不同的地方 s = s1.symmetric_difference(s2) print(s) # s1 s2中相同的地方 s = s1.intersection(s2) print(s) #合併兩個set s = s1.union(s2) print(s) #s1是不是s2的子集 s=s1.issubset(s2) print(s) # s1是不是s2的超集 s = s1.issuperset(s2) print(s) return s1.symmetric_difference(s2)
