Programming Concepts Lecture

Overview

• Lecture focused on initiating and modifying class attributes in Python.

Key Concepts

Class Initialization and Attributes

• __init__ method is used to initialize class attributes.
• Example of setting attributes:

  def __init__(self):
      self.price = 0
      self.RAM = ''
      self.processor = ''
  

• Assign values like self.price = 0

Modifying Attributes

• Attributes can be modified outside the class using object attributes (e.g., object.attribute = value).
• Example of modifying RAM and processor:

  HP.RAM = '16GB'
  HP.processor = 'i7'
  

Display Method

• Creating a method to display object attributes
• Example:

  def display(self):
      print(f'Price: {self.price}, RAM: {self.RAM}, Processor: {self.processor}')
  

Practical Application

• Initiated objects for HP and Dell laptops.
• Modified attributes such as RAM and processor for these objects.
• Used the display method to print the object's attributes.
• Example instantiation and method call:

  HP = Laptop()
  HP.RAM = '8GB'
  HP.processor = 'i5'
  HP.display()
  

Importance of Proper Initialization

• Ensures that all necessary attributes are available for methods and future modifications.

Conclusion

• Emphasis on understanding the setup of class attributes and methods for effective programming.
• Next class to delve deeper into object-oriented programming concepts.
