• How to write and read a JSON file
• What is *args and how to use it
• What is **kwargs and how to use it
• How to handle named arguments in a function

0. If it's not tested it doesn't work

• All your files, classes and methods must be unit tested and be PEP 8 validated.

1. Base class

• Write the first class Base:

2. First Rectangle

• Write the class Rectangle that inherits from Base:

3. Validate attributes

• Update the class Rectangle by adding validation of all setter methods and instantiation (id excluded):

4. Area first

• Update the class Rectangle by adding the public method def area(self): that returns the area value of the Rectangle instance.

5. Display #0

• Update the class Rectangle by adding the public method def display(self): that prints in stdout the Rectangle instance with the character # - you don’t need to handle x and y here.

6. str

• Update the class Rectangle by overriding the str method so that it returns [Rectangle] () / - /

7. Display #1

• Update the class Rectangle by improving the public method def display(self): to print in stdout the Rectangle instance with the character # by taking care of x and y

8. Update #0

• Update the class Rectangle by adding the public method def update(self, *args): that assigns an argument to each attribute:

9. Update #1

• Update the class Rectangle by updating the public method def update(self, *args): by changing the prototype to update(self, *args, **kwargs) that assigns a key/value argument to attributes:

10. And now, the Square!

• Write the class Square that inherits from Rectangle:

11. Square size

• Update the class Square by adding the public getter and setter size

12. Square update

• Update the class Square by adding the public method def update(self, *args, **kwargs) that assigns attributes:

13. Rectangle instance to dictionary representation

• Update the class Rectangle by adding the public method def to_dictionary(self): that returns the dictionary representation of a Rectangle:

14. Square instance to dictionary representation

• Update the class Square by adding the public method def to_dictionary(self): that returns the dictionary representation of a Square:

15. Dictionary to JSON string

• JSON is one of the standard formats for sharing data representation.

16. JSON string to file

• Update the class Base by adding the class method def save_to_file(cls, list_objs): that writes the JSON string representation of list_objs to a file:

17. JSON string to dictionary

• Update the class Base by adding the static method def from_json_string(json_string): that returns the list of the JSON string representation json_string:

18. Dictionary to Instance

• Update the class Base by adding the class method def create(cls, **dictionary): that returns an instance with all attributes already set:

19. File to instances

• Update the class Base by adding the class method def load_from_file(cls): that returns a list of instances:

20. JSON ok, but CSV?

• Update the class Base by adding the class methods def save_to_file_csv(cls, list_objs): and def load_from_file_csv(cls): that serializes and deserializes in CSV:

21. Let's draw it

• Update the class Base by adding the static method def draw(list_rectangles, list_squares): that opens a window and draws all the Rectangles and Squares:
