Python - Classes and Objects

In this project, I began practicing object-oriented programming using classes and objects in Python. I learned about attributes, methods, and properties as well as data abstraction, data encapsulation, and information hiding.

Tasks 📃

• 0. My first square

  • 0-square.py: Python class Square that defines a square.

• 1. Square with size

  • 1-square.py: Python class Square that defines a square. Builds on 0-square.py with:
    • Private instance attribute size.
    • Instantiation with size.

• 2. Size validation

  • 2-square.py: Python class Square that defines a square. Builds on 1-square.py with:
    • Instantiation with optional size: def __init__(self, size=0):
  • If a provided size attribute is not an integer, a TypeError exception is raised with the message must be an integer.
  • If a provided size attribute is less than 0, a ValueError exception is raised with the message size must be >= 0.

• 3. Area of a square

  • 3-square.py: Python class Square that defines a square. Builds on 2-square.py with:
    • Public instance attribute def area(self): that returns the current square area.

• 4. Access and update private attribute

  • 4-square.py: Python class Square that defines a square. Builds on 3-square.py with:
    • Property def size(self): to retrieve the private instance attribute self.
    • Property setter def size(self, value): to set self.

• 5. Printing a square

  • 5-square.py: Python class Square that defines a square. Builds on 4-square.py with:
    • Public instance method def my_print(self): that prints the square with the character # to standard output (if size == 0 -> prints an empty line).

• 6. Coordinates of a square

  • 6-square.py: Python class Square that defines a square. Builds on 5-square.py with:
    • Private instance attribute position.
    • Property def position(self): to retreive position.
    • Property setter def position(self, value): to set position.
    • Instantiation with optional size and position: def __init__(self, size=0, position=(0, 0)):
  • If a provided position attribute is not a tuple of two integers, a TypeError exception is raised with the message position must be a tuple of 2 positive integers.
