python 函数请教正确写法

Question

arrData= [
{"name":"小明","age":18},
{"name":"小张","age":10},
{"name":"小明","age":18},
]

查找,name为小明, age为18,有几个,也许会有多个条件,所以要用for
下面写法错误
def search_field(arr, **kwargs):#
    def iterator_obj(obj):
        result = False
        for i in kwargs:
            if obj[i] == kwargs[i]:
                result = True
        return result
    return filter(iterator_obj, arr)

search_field(arrData, {'name':"小明",'age':18})

请教正确写法

Answer 1

关键字参数传错了，应该下面这样传。同时过滤函数默认result =True，不相等直接 return False就行

arrData= [
{"name":"小明","age":18},
{"name":"小张","age":10},
{"name":"小明","age":18},
{"name":"小明","age":16},
]
def search_field(arr, **kwargs):#
    def iterator_obj(obj):
        result = True
        for i in kwargs:
            if obj[i] != kwargs[i]:
                return False
        return result
    return filter(iterator_obj, arr)
result=search_field(arrData, name="小明",age=18)
print(list(result))
