def has_duplicates(lst):return len(lst) != len(set(lst))x = [1,2,3,4,5,5]y = [1,2,3,4,5]has_duplicates(x)# Truehas_duplicates(y)# False 19、合并两个字典 下面的方法将用于合并两个字典。 defmerge_two_dicts(a, b):c = a.copy# make a copy of ac.update(b)# modify key...
It then prints the original sets, followed by the difference between color_list_1 and color_list_2 (the elements in color_list_1 that are not in color_list_2) and the difference between color_list_2 and color_list_1 (the elements in color_list_2 that are not in color_list_1). He...
