# Import ParentClass object
from .parent_class import ParentClass


# Create a child class with inheritance
class ChildClass(ParentClass):

        # Call parent's __init__ method
        ParentClass.__init__(self)

        # Add attribute unique to child class
        self.child_attribute = "I'm a child class attribute!"


# Create a ChildClass instance
child_class = ChildClass()
print(child_class.child_attribute)
print(child_class.parent_attribute)
