Python Classes and Objects


Tasks


  • 0.My first square

  • 1.Sqaure 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
    • 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.

  • 7. Singly linked list

    • 100-singly_linked_list.py: Python classes Node and SinglyLinkedList that define a node of a singly-linked list and a singly-linked list. The class Node is defined with:

    • Private instance attribute data.
    • Property def data(self): to set data.
    • Property setter def data(self, value): to set data.
    • Private instance attribute next_node.
    • Property def next_node(self, value): to set next_node.
    • Instantiation with data and next_node: def __init__(self, data, next_node=None):
    • If a provided data attribute is not an integer, a TypeError exception is raised with the message data must be an integer.
    • If a provided next_node attribute is not a Node or None, a TypeError exception is raised with the message next_node must be a Node object.
    • The class SinglyLinkedList is defined with:
      • Private instance attribute head.
      • Instantiation def __init__(self):
      • Public instance method def sorted_insert(self, value): that inserts a new Node into the correct sorted position in the list increasing order).

  • 8. Print Square instance

    • 101-square.py: Python class Square that defines a square. Builds on 6-square.py with: Method __str__ to set printing of a Square instance equivalent to my_print().

  • 9. Compare 2 squares

    • 102-square.py: Python class Square that defines a square. Builds on 101-square.py with: Methods __eq__, __ne__, __lt__, __le__, __gt__, and __ge__, to enable usage of Square instances with logical operators ==, !=, <, <=, >, and >=, respectively, based on the square area.

  • 10. ByteCode -> Python
