TypeError:__ init __()采用0位置参数,但给出了1

Question

我刚刚开始在我的学校编写代码,我正在学习如何使用Python.我们老师给了我们这个任务:

1. 创建一个类,并将其命名为"CustomerInfo".
2. 创建一个没有参数的构造函数(仅限self).
3. 为名称,订单,数量和地址创建用户输入.
4. 为名称,顺序,数量和地址创建mutator方法.
5. 为名称,订单,数量和地址创建存取方法.
6. 创建一个新的CustomerInfo()对象并将其命名为"customer1".
7. 打印出客户信息.

这是我的代码:

class CustomerInfo:

    def __init__ ():
        self.name = theName
        self.order = theOrder
        self.quantity = theQuantity
        self.address = theAddress

    def setName( self, newName ):
        self.Name = newName
    def setOrder ( self, newModel ):
        self.model = newModel
    def setQuantity ( self, newQuantity ):
        self.quantity = newQuantity
    def setAddress (self, newAddress ):
        self.address = newAddress

    def getName ( self ):
        return self.name
    def getOrder ( self ):
        return self.order
    def getQuantity ( self ):
        return self.quantity
    def getAddress ( self ):
        return self.address

name = input("Enter your name: ")
order = input("Enter your order: ")
quantity = int(input("Enter your quanity: "))
address = input("Enter your address: "))

customer1 = CustomerInfo()

print ( "Name: ", customer1.name)
print ( "Order: ", customer1.order)
print ( "Quanity: ", customer1.quantity)
print ( "Address: ", customer1.address)

但是,我得到以下错误:

TypeError: __init__() takes 0 positional arguments but 1 was given

我说(self)要__init__在注释中的描述,现在当我运行该模块的输入工作,但我把名字顺序,数量和地址的输入后,结果出来是这样的:

Traceback (most recent call last):
File line 32, in <module>
    customer1 = CustomerInfo()
File line 4, in __init__
    self.name = theName
NameError: name 'theName' is not defined

Answer 1

该__init__方法需要self在Python中接受,因为它是一种方法.

更改:

def __init__ ():

至:

def __init__ (self):
