Study Notes
Object-Oriented Programming
- Object-oriented programming involves defining classes which encapsulate data and behavior.
- Key component of object-oriented design.
Methods
- Procedures that objects can perform are called methods.
- Methods allow actions to manipulate object data.
Mutator Methods
- Also known as setters, mutator methods enable the modification of attribute values.
UML
- Stands for Unified Modeling Language, a standardized way to visualize the design of a system.
Accessor Methods
- Accessor methods provide a secure way to obtain attribute values without allowing modification from outside the class.
Constructor Method
- The special method
__init__is automatically called when a new instance of a class is created, initializing the object's attributes.
Self Parameter
- The
selfparameter is used to reference the specific object on which a method operates, distinguishing between object and method context.
Data Hiding
- Object-oriented programming allows for data encapsulation, meaning an object's internal data can be hidden from external code.
Self Parameter Requirement
- The self parameter is mandatory in all class methods to ensure proper reference to object attributes and methods.
Class as a Blueprint
- A class serves as a blueprint for creating objects, defining the structure and behavior that instances of the class will have.
