Class takes no arguments - Myang123 - Jul-09-2019

Hey,

I am writing a basic class and I am having problems inserting arguments into the class "Dog".

Here is the source code

class Dog():
    def _init_(self, name, age):
        self.name = name
        self.age = age

    def sit(self):
        print(self.name.title() + ' is now sitting.')

    def roll_over(self):
        print(self.name.title() + ' is now rolling over.')


my_dog = Dog('Willie', 6)
print("my dog's name is " + my_dog.name.title() + ".")
print('my dog is ' + str(my_dog.age) + '.')

here is the error message:

Error:Traceback (most recent call last):
  File "C:/Users/maxya/PycharmProjects/classes.py", line 28, in <module>
    my_dog = Dog('Willie', 6)
TypeError: Dog() takes no arguments

Thank you for your help.

The dunder init method is double underscore on each side __init__

Hello Myang123,

I saw this same problem and one question I had was already answered, but I had another that I hope you can help with.

How did you get the line below to work?

my_dog = Dog("Peso")

I placed it outside the code block(>>>) and inside the code block(...) and both failed.

The return message is(...) invalid syntax and (>>>) Dog is not defined.

I am hoping that you are able to point me in the right direction.

Thanks!
