TypeError: method takes 0 positional arguments but 1 was given in Python

Hi guys. 

I just recently started coding at my school and am learning to use Python. And I created an object class CustomerInfo as below:

class CustomerInfo:
    def __init__ ():
        self.name = name
        self.order = order
        self.quantity = quantity
        self.address = address

    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 quantity: "))
address = input("Enter your address: ")

customerObj = CustomerInfo()

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

I want to take input some information of customers like name, order, quantity and address but I get an exception TypeError: __init__() takes 0 positional arguments but 1 was given.

Enter your name: Python
Enter your order: 23
Enter your quantity: 21
Enter your address: 333 West USA
Traceback (most recent call last):
  File "main.py", line 32, in <module>
    customerObj = CustomerInfo()
TypeError: __init__() takes 0 positional arguments but 1 was given

How can I fix it? Anyone can explain to me.

Thanks for any suggestions.

    Method __init__ () should be accepted self in Python because, well, it's a method.


    def __init__ ():


    def __init__ (self):

    And it solved the issue for you.

    Hey, I think this is the message throw when you forget (self,...) arg in __init__() or any other method.

    Add self param and it is solved for you.
