Part 1. 1. Design a UML class Book with at least 3 attributes and 2 methods. On top of the provided methods, you are to create your 2 overloaded init() methods (look at the next question). Use proper Python Naming convension. 2. Based on the given UML in item 1. Create a Python class that contains all the declered attributes and methods from the UML. Also include two (2) init() methods. The first one should provide a default value for the object: ie: an empty string, while the second init() method should be able to accept parameters for object initialization. 3. Instantiate / Create 2 objects, the first one should use the default init() method, while the second object should pass values that will automatically assign properties on the object. 4. Create an str method that will print the identity of the objects created in item 3. Once the methods were created inside the class, use it to print the identity of the objects created in item 3. Part 2. 5. Create your own class hierarchy with 3 layers. Provide any numbers of attributes and methods for each class. Overload the init() methods. 6. Instantiate 2 objects for each class, use the different init() methods. 7. Create a list / array of objects. Iterate through them and print all the details of each object. Take a screenshot of the output and give me the link here:

Part 1. 1. Design a UML class Book with at least 3 attributes and 2 methods. On top of the provided methods, you are to create your 2 overloaded __init__() methods (look at the next question). Use proper Python Naming convension. 2. Based on the given UML in item 1. Create a Python class that contains all the declered attributes and methods from the UML. Also include two (2) __init__() methods. The first one should provide a default value for the object: ie: an empty string, while the second __init__() method should be able to accept parameters for object initialization. 3. Instantiate / Create 2 objects, the first one should use the default __init__() method, while the second object should pass values that will automatically assign properties on the object. 4. Create an str method that will print the identity of the objects created in item 3. Once the methods were created inside the class, use it to print the identity of the objects created in item 3.
