# 获取list_all list_all = list1 + [item for item in list2 if item not in list1] # 显式给list_all排序 list_all.sort(cmp=lambda x,y: cmp(x['score'], y['score']), reverse=True) # 获取list_new list_new = [item for item in list2 if item in list1] # 显式给list_new排序 list_new.sort(cmp=lambda x,y: cmp(x['score'], y['score']), reverse=True)

set1 = set([frozenset(i.items()) for i in list1]) set2 = set([frozenset(i.items()) for i in list2]) list_all = sorted(set1|set2,key = lambda k:dict(k)['score'],reverse = True) list_new = sorted(set1&set2,key = lambda k:dict(k)['score'],reverse = True)

set() 不能处理非hashable数据, 会报错的, 参见三楼的frozenset

list(set(list1).add(list2))
