basic class and objects example

Dog.py

class Dog():
    total_dogs = 0
    def __init__(self, name):
        self.name = name
        # every time you initialize you add to the class variable
        Dog.total_dogs += 1

    def speak(self):
        # you need to pass self as a parameter for instance methods
        return 'woof!'
    
    @staticmethod
    # if you have @classmethod you have to pass Dog as a parameter
    def count_dogs():
        return Dog.total_dogs

tilly = Dog('tilly')
ruby = Dog('ruby')
print(vars(tilly))
# with vars you get back a dictionary of object attributes
print(tilly.speak())
print(Dog.count_dogs())
