Base Class with Function.py

# Let's create a base class called Pets with a function called
# get_attributes. The base class has a __init__ constructor
# method in it, which means that any functions inside the base
# class will be able to use the attributes from the __init__
# constructor method. For example, the self.dog attribute is
# inside the get_attributes function, while the a.dog attribute
# is outside the Pets class and the get_attribute function. Take
# a close look at the 'print' statement outside the Pets class.

class Pets:
    def __init__(self,dog,cat,bird,fish):
        self.dog=dog;self.cat=cat
        self.bird=bird;self.fish=fish

    def get_attributes(self): # (self) calls itself to get the attribute values we want.
        print('I got the',self.dog,'attribute from the function \
get_attributes, through the base class Pets.')

a=Pets('Dog','Cat','Bird','Fish') # attribute values from the Pets class

print('I got the',a.dog,'attribute right from the base class Pets.')

Pets.get_attributes(a) # call the function get_attributes, via the Pets class.

# This Pets class Python program example is exactly the
# same as the Pets class Python program example above.
# However, without a __init__ constructor method, the program
# looks rather bulky and cluttered.

class Pets:
    def get_attributes(self):  # (self) calls itself to get the attribute values we want.
        print('I got the',self.dog,'attribute from the function \
get_attributes, through the base class Pets.')

a=Pets()
a.dog='Dog'
a.cat='Cat'
a.bird='Bird'
a.fish='Fish'  # attribute values from the Pets class

print('I got the',a.dog,'attribute right from the base class Pets.')

Pets.get_attributes(a) # call the function get_attributes, via the Pets class.
