Why am I getting a TypeError when I seem to be filling the paremeters? [closed]-CodePudding

I am trying to create an object and I'm initializing it with 2 fields first (name & number). However each time I run the program I'm given this error:

TypeError: __init__() missing 1 required positional argument: 'number'

The __init__ method in the class looks like this:

    def __init__(self, name, number):
    self.__name__ = name
    self.__number__ = number

The code where I try to create the object is this:

employee1 = ProductionWorker(Employee)

name = input("Enter employee name:")
number = input("Enter employee number:")

employee1.__init__(name, number)

Does anyone know why I may be getting this error?

CodePudding user response：

Do:

name = input("Enter employee name:")
number = input("Enter employee number:")

employee1 = ProductionWorker(name, number)

You do not generally need to call __init__ explicitly; it's invoked by the ProductionWorker(...) expression, which passes its arguments to self.__init__ as part of initialization.

You do not need to restate when constructing a new object that Employee is the parent class; that only needs to be said when the class is defined.

CodePudding user response：

You are using the class as a parameter. Then, init is always automatically called on creation. This how it might work as You want (using the show method to validate):

class Employee:
    def __init__(self, name, number):
        self.__name__ = name
        self.__number__ = number
    

    def show(self):
        print(self.__name__)
        print(self.__number__)
    

name = input("Enter employee name:")
number = input("Enter employee number:")
employee1 = Employee(name,number)
employee1.show()
