python object()不带参数错误

我无法相信这实际上是一个问题,但我一直在尝试调试此错误而我无处可去。我确定我错过了一些非常简单的东西,因为这看起来很傻。

import Experiences, Places, Countries
class Experience(object):

    def make_place(self, place):
        addr = place["address"]
        addr = Places.ttypes.Address(addr["street"], addr["city"], addr["state"], Countries.ttypes._NAMES_TO_VALUES[addr["country"]], addr["zipcode"])
        ll = Geocoder.geocode(addr["street"]+", "+addr["city"]+", "+addr["state"]+" "+addr["zipcode"])
        place["location"] = Places.ttypes.Location(ll[0].coordinates[0], ll[0].coordinates[1])

    def __init__(self, exp_dict):
        exp_dict["datetimeInterval"] = Experiences.ttypes.DateTimeInterval(remove(exp_dict, "startTime"), remove(exp_dict, "endTime"))
        exp_dict["type"] = Experiences.ttypes.ExperienceType.OPEN
        exp_dict["place"] = self.make_place(exp_dict["place"])
        self.obj = Experiences.ttypes.Experience(**exp_dict)

@client.request
@client.catchClientException
def addExperience(thrift, access_token, exp_dict):
    experience = Experience(exp_dict)
    return thrift.client.addExperience(thrift.CLIENT_KEY, access_token, experience.obj)

(对应于addExperience的两个装饰器是因为它是在声明其类的文件之外定义的。)

我得到的错误是:

experience = Experience(exp_dict)
TypeError: object() takes no parameters

所以这对我没有任何意义,因为我明确地声明了init函数的第二个参数。任何帮助都会很棒!

这是Experience.mro() - 它表示类体验的正确模块位置:

[<class 'hangify.client.exp.Experience'>, <type 'object'>]

这是dir(经验):

 ['__class__', '__delattr__', '__dict__', '__doc__', '__format__',
 '__getattribute__', '__hash__', '__init__', '__module__', '__new__',
 '__reduce__', '__reduce_ex__', '__repr__', '__setattr__',
 '__sizeof__', '__str__', '__subclasshook__', '__weakref__', 'make_place']

答案 0 :(得分:61)

您混合了标签和空格。 __init__实际上是嵌套在另一个方法中的,因此您的类没有自己的__init__方法,而是继承object.__init__。在记事本中打开你的代码,而不是你正在使用的任何编辑器,你会看到你的代码,因为Python的选项卡处理规则可以看到它。

这就是为什么你不应该混合标签和空格。坚持一个或另一个。建议使用空格。

答案 1 :(得分:37)

我在这方面挣扎了一段时间。 __init__的愚蠢规则。它是两个“_”一起成为“__”

答案 2 :(得分:18)

我也遇到了这个错误。顺便说一句,我输入了 __ int __ 而不是 __ init __

我认为,在许多错误的情况下,我使用的IDE(IntelliJ)会将颜色更改为功能定义的默认设置。但是,在我的情况下 __ int __ 是另一个dunder / magic方法,颜色与IDE显示的 __ init __ (默认的预定义项目定义颜色)相同,这让我有些不同是时候发现失踪的 i

答案 3 :(得分:7)

您必须每次按两次并按( _ )键,它必须如下所示:

__init__
