Project: 0x0C. Python - Almost a circle

This directory contains projects focused on understanding and implementing various Python concepts such as classes, inheritance, and unit testing. The tasks cover creating and managing classes, serialization/deserialization, and writing unit tests.

Learning Objectives

General

  • What is Unit testing and how to implement it in a large project
  • How to serialize and deserialize a Class
  • 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

Tasks

Task File Description
0. If it's not tested it doesn't work tests/ Write unit tests for the classes and methods. (Not implemented yet)
1. Base class models/base.py, models/init.py Write a class Base with private class attribute __nb_objects and a class constructor.
2. First Rectangle models/rectangle.py Write a class Rectangle that inherits from Base.
3. Validate attributes models/rectangle.py Update the class Rectangle by adding validation of all setter methods and instantiation.
4. Area first models/rectangle.py Update the class Rectangle by adding the public method def area(self): that returns the area value of the Rectangle instance.
5. Display #0 models/rectangle.py Update the class Rectangle by adding the public method def display(self): that prints in stdout the Rectangle instance with the character #.
6. str models/rectangle.py Update the class Rectangle by overriding the __str__ method to return a custom string representation.
7. Display #1 models/rectangle.py Update the class Rectangle by enhancing the def display(self): method to handle x and y coordinates.
8. Update #0 models/rectangle.py Update the class Rectangle by adding the public method def update(self, *args): that assigns an argument to each attribute.
9. Update #1 models/rectangle.py Update the class Rectangle by updating the public method def update(self, *args, **kwargs): to assign a key/value argument to attributes.
10. And now, the Square! models/square.py Write a class Square that inherits from Rectangle.
11. Square size models/square.py Update the class Square by adding the public getter and setter size.
12. Square update models/square.py Update the class Square by adding the public method def update(self, *args, **kwargs): that assigns attributes.
13. Rectangle instance to dictionary representation models/rectangle.py 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 models/square.py 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 models/base.py Update the class Base by adding the static method def to_json_string(list_dictionaries): that returns the JSON string representation of list_dictionaries.
16. JSON string to file models/base.py 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 models/base.py 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 models/base.py 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 models/base.py 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? models/ Update the class Base by adding methods to handle CSV serialization and deserialization.
21. Let's draw it models/base.py Update the class Base by adding a static method def draw(list_rectangles, list_squares): that opens a window and draws all the Rectangles and Squares.
