# 43. Inheritance

"""
# Inheritance allows us to define a class that inherits all the methods and properties from
    another class.
# To create a class that inherits the functionality from another class, send the parent class as a
    parameter when creating the child class.
# When you add the __init__() function, the child class will no longer inherit the parent's
    __init__() function.
# Note: The child's __init__() function overrides the inheritance of the
    parent's __init__() function.
# To keep the inheritance of the parent's __init__() function, add a call to the parent's
    __init__() function: parent.__init__(...,...,..)
