What Is Object-Oriented Programming (OOP)?

Austin did an excellent job of clearly explaining the various OOP topics in all 7 videos, without leaving any gaps or questions. Now, I’m anxiously waiting for the next set of OOP videos to continue to this course & I hope they show up soon. IMHO, there aren’t enough OOP topics in realpython.com or dbader.org, but there are tons of other Python-related topics in both sites!

Thanks for your feedback Peter, that’s great to hear. Stay tuned for more Python OOP tutorials and video courses in the future :)

Thanks for the kind words Peter, I’m glad to hear the course was helpful for you.

It’s very helpful course. Absolutely nice. Thanks a lot!

Hello ! Thanks for the course ! I was exercising and wanted to create an instance attribute of type ‘Wear’ for my dogs. For it to work I had to explicitly name the class in the init of Dog():

def __init__(self, name, age, cloth=Wear):

I’m affraid that I won’t be able to understand… but why this doesn’t work like the other types?

def __init__(self, name, age, cloth):

@Sillikone Hi, there. Can you clarify your question, please? I’m afraid folks over here may not be able to understand it correctly.

If you want to create an instance variable of a specific type, then you should state that explicitly in your .__init__() method:

class Dog:
    def __init__(self, name, age):
        self.name = name
        self.age = age
        self.cloth = Wear()  # <--- Here

However, your function accepts the cloth as a parameter, so perhaps this is what you meant instead?

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

@Bartosz Zaczyński Hi ! Sorry for the trouble, yersterday this wasn’t working:

class Wear:
    def __init__(self, color):
        self.color = color

class Dog:
    def __init__(self, name, cloth):
        self.name = name
        self.cloth = cloth

shirt = Wear('red')
dog = Dog('Luigi', shirt)
print(f'{dog.name} is wearing a {dog.cloth.color} cloth')

I had to specify this for it to work:

class Dog:
    def __init__(self, name, cloth=Wear):
        self.name = name
        self.cloth = cloth

Rewritting all from scratch to clarify, I could not reproduce the behavior.
