Python - Inheritance

Tasks 📃

• 0. Lookup

  • 0-lookup.py: Python function that returns a list of available attributes and methods of an objects.

• 1. My list

  • 1-my_list.py: Python class MyList that inherits from list. Includes:
    • Public instance method def print_sorted(self): that prints the list in ascending sorted order (assumes all list elements are ints).

• 2. Exact same object

  • 2-is_same_class.py: Python function that returns True if an object is exactly an instance of a specified class; otherwise False.

• 3. Same class or inherit from

  • 3-is_kind_of_class.py: Python function that returns True if an object is an instance or inherited instance of a specified class; otherwise False.

• 4. Only sub class of

  • 4-inherits_from.py: Python function that returns True if an object is an inherited instance (either directly or indirectly) from a specified class; otherwise False.

• 5. Geometry module

  • 5-base_geometry.py: An empty Python class BaseGeometry.

• 6. Improve Geometry

  • 6-base_geometry.py: Python class BaseGeometry. Builds on 5-base_geometry.py with:
    • Public instance method def area(self): that raises an Exception with the message area() is not implemented.

• 7. Integer validator

  • 7-base_geometry.py: Python class BaseGeometry. Builds on 6-base_geometry.py with:
    • Public instance method def integer_validator(self, name, value): that validates the parameter value.
    • Assumes the parameter name is always a string.
    • The parameter value must be an int, otherwise, a TypeError exception is raised with the message <name> must be an integer.
    • The parameter value must be greater than 0, otherwise, a ValueError exception is raised with the message <value> must be greater than 0.

• 8. Rectangle

  • 8-rectangle.py: Python class Rectangle that inherits from BaseGeometry (7-base_geometry.py). Includes:
    • Private attributes width and height - validated with integer_validator.
    • Instantiation with width and height: def __init__(self, width, height):

• 9. Full rectangle

  • 9-rectangle.py: Python class Rectangle that inherits from BaseGeometry (7-base_geometry.py). Builds on 8-rectangle.py with:
    • Implementation of the method area().
    • Special method __str__ to print Rectangles in the format [Rectangle] <width>/<height>.

• 10. Square #1

  • 10-square.py: Python class Square that inherits from Rectangle (9-rectangle.py). Includes:
    • Private attribute size - validated with integer_validator.
    • Instantiation with size: def __init__(self, size):.
    • Implementation of the area() method.

• 11. Square #2

  • 11-square.py: Python class Square that inherits from Rectangle (9-rectangle.py). Builds on 10-square.py with:
    • Special method __str__ to print squares in the format [Square] <width>/<height>.

• 12. My integer

  • 100-my_int.py: Python class MyInt that inherits from int. Includes:
    • Inversion of the == and != operators.

• 13. Can I?

  • 101-add_attribute.py: Python function that adds a new attribute to an object if possible.
    • If an attribute cannot be added, a TypeError exception is raised with the message can't add new attribute.
