TypeError: method() takes 1 positional argument but 2 were given

Question

If I have a class...

class MyClass:

    def method(arg):
        print(arg)

...which I use to create an object...

my_objec         


        

Answer 1

It occurs when you don't specify the no of parameters the __init__() or any other method looking for.

For example:

class Dog:
    def __init__(self):
        print("IN INIT METHOD")

    def __unicode__(self,):
        print("IN UNICODE METHOD")

    def __str__(self):
        print("IN STR METHOD")

obj=Dog("JIMMY",1,2,3,"WOOF")

When you run the above programme, it gives you an error like that:

TypeError: __init__() takes 1 positional argument but 6 were given

How we can get rid of this thing?

Just pass the parameters, what __init__() method looking for

class Dog:
    def __init__(self, dogname, dob_d, dob_m, dob_y, dogSpeakText):
        self.name_of_dog = dogname
        self.date_of_birth = dob_d
        self.month_of_birth = dob_m
        self.year_of_birth = dob_y
        self.sound_it_make = dogSpeakText

    def __unicode__(self, ):
        print("IN UNICODE METHOD")

    def __str__(self):
        print("IN STR METHOD")


obj = Dog("JIMMY", 1, 2, 3, "WOOF")
print(id(obj))
