# 44. Inheritance 2

"""
# Python also have a super() function that will make the child class inherit all the methods and
    properties from its parent
    # By using the super() function, you do not have to use the name of the parent element, it will
        automatically inherit the methods and properties from its parent.
# If you add a method in the child class with the same name as a function in the parent class,
    the inheritance of the parent method will be overridden.
