我不能相信这实际上是一个问题,但我一直在试图调试这个错误,而且我已经无处可去。我确信我错过了一些非常简单的事情,因为这看起来很愚蠢。python对象()不需要参数错误

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) 

(这两个相当于addExperience装饰是因为这是它的类声明的文件外定义。)

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,因为我清楚地声明了init函数的第二个参数。任何帮助都是极好的!

什么是经验'什么是'Experiences.ttypes'? – BrenBarn

但我认为这并不相关。例如,当我从继承链中删除对象时,错误就变成了“TypeError:这个构造函数不带参数”。 – eatonphil

你已经混合了制表符和空格。 __init__实际上是嵌套在另一个方法中的,所以你的类没有__init__方法,而是调用object.__init__。在记事本中打开你的代码,而不是你使用的任何编辑器,你会看到你的代码为Python的标签处理规则。

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。

我知道它必须是那样的愚蠢。感谢智慧! – eatonphil

必须按自来水两次(_)键每次,它必须看起来像:

__init__

问题包含正确的'__init__'。 – igaurav

我挣扎了一会儿这个问题。愚蠢的规则为__init__。这是两个“_”在一起是“__”

得到这个错误,因为我很sl and,只写'__init()' – citynorman

得到这个错误,因为我很sl and,只写** _init _()** –

得到这个错误,因为我很蠢,并写了'___ init ___()'。 – kennycoc

我也得到了这个错误。顺便说一句,我输入__int__而不是__init__

我认为,在许多错误类型的情况下,我使用的IDE(IntelliJ)会将颜色更改为函数定义的默认设置。但是,在我的情况__int__是另一个dunder /魔术方法,颜色保持一样的其中一个IDE显示为__init__(默认预定义项定义色彩),它花了一些时间在发现失踪
