- Overview: Discusses the importance of classes and objects in Python for organizing and enhancing programs.
- Real-World Modeling: Explains how classes and objects allow for modeling real-world entities that can't be represented by basic data types like strings or numbers.
- Creating Custom Data Types: Demonstrates how to create custom data types using classes, using the example of a
Student
class.
- Creating a Class: Shows how to define a class in Python, using
class ClassName:
. - Initialization Function: Explains the use of the
__init__
function for initializing class attributes. - Attributes: Discusses defining attributes like
name
,major
,GPA
, andis_on_probation
within a class.
- Instantiating Objects: Covers creating instances of a class, known as objects.
- Assigning Values to Objects: Details how to assign values to object attributes during instantiation.
- Defining Functions in Classes: Illustrates how to define functions within a class that can operate on object attributes.
- Example Function: Provides an example function
on_honor_roll
to determine if a student's GPA qualifies for the honor roll.
- Concept of Inheritance: Introduces the concept of inheritance in Python, where a class can inherit attributes and methods from another class.
- Creating Inherited Classes: Shows how to create a class that inherits from another, using the example of a
ChineseChef
class inheriting from aChef
class. - Overriding Methods: Discusses how inherited classes can override methods from the parent class.
- Chef Class Example: Uses the example of a
Chef
class with methods likemake_chicken
andmake_special_dish
. - Chinese Chef Extension: Explores extending the
Chef
class to aChineseChef
class, demonstrating inheritance and method overriding.
