# To create a class that uses inheritance and polymorphism
# from another class:
class Rectangle(Shape):

# Class variables refer to variables that are made within a class.
# It is generated when you define the class.
# It's shared with all the instance of that class.
# Example:
class some_variable_holder(object):
var = "This variable is created inside the class some_variable_holder()."
def somefunc(self):
print("Random function ran.")
thing = some_variable_holder()
another_thing = some_variable_holder()
# Both does the same thing because the same variable has been passed on from the class.
