19.合并两个词典 以下方法可用于合并两个词典。 def merge_two_dicts(a, b): c = a.copy() # make a copy of a c.update(b) # modify keys and values of a with the ones from b return c a = { 'x': 1, 'y': 2} b = { 'y': 3, 'z': 4} print(merge_two_dicts(a, b))...
defdiff(a,b): set_a=set(a) set_b=set(b) comparison=set_a.difference(set_b)returnlist(comparison)print(diff([1,2,3],[1,2,4])) 输出:[3] 15.通过函数取差(如下方法会先应用一个给定的函数,然后再返回应用函数后结果有差别的列表的元素) importmathdefdifference_by(a,b,fn): b=set(map...
