python object（）没有参数错误

Question

我不敢相信这实际上是一个问题，但是我一直在尝试调试此错误，但是却一无所获。我敢肯定我错过了一些非常简单的事情，因为这看起来太愚蠢了。

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)

（与addExperience对应的两个装饰器是因为这是在声明其类的文件外部定义的。）

我得到的错误是：

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

所以这对我来说没有任何意义，因为我清楚地声明了init函数的第二个参数。任何帮助都是极好的！

这是Experience.mro（）-这表示类Experience的正确的模块方式位置：

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

这是dir（Experience）：

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

您混用了制表符和空格。__init__实际上是在另一个方法中嵌套定义的，因此您的类没有自己的__init__方法，而是继承了object.__init__。在记事本中打开代码，而不要使用任何编辑器，您将在Python的制表符处理规则看到它的同时看到代码。

这就是为什么您永远不要混用制表符和空格的原因。坚持一个或另一个。建议使用空格。
