CarParts

This Python project implements a flexible system for creating custom vehicles using a combination of design patterns. Users can configure and build various types of vehicles (cars, trucks, etc.) with a wide range of specifications, including color, engine, and equipment..

Key Features:

Extensive customization: Users can tailor their vehicles with a variety of options, such as different engine types, colors, and accessories. Diverse vehicle types: Supports the creation of various vehicle types, including cars, trucks, and more. Cloning existing vehicles: Users can create copies of existing vehicles and modify them to suit their specific needs. Implementation of design patterns: Singleton: For managing a centralized database of vehicle components. Factory Method: For creating different types of vehicle components. Abstract Factory: For creating families of related components. Builder: For constructing vehicles step-by-step. Prototype: For cloning existing vehicles. Modular structure: The project is designed with a modular structure for easy maintenance and expansion. Comprehensive testing: Unit and integration tests ensure the system's reliability. Project Structure:

Main file: Contains the core logic of the application, including classes for vehicles, components, factories, and builders. Database file: Stores information about vehicle components and configurations. Test file: Contains unit and integration tests to verify the system's functionality. Usage:

Install dependencies: Install the required dependencies to run the project. Run the application: Execute the application and configure your desired vehicle through the user interface or command line. Create vehicle: The system will automatically create your vehicle based on the selected configuration. Technologies:

Programming language: Python Design patterns: Singleton, Factory Method, Abstract Factory, Builder, Prototype Target audience:

Software developers interested in design patterns Computer science students Individuals looking to learn about building complex systems with Python
