🚗 Uber Python OOP Practice Proj

Overview

We'll be build a mini Uber simulation in Python using object-oriented programming (OOP).
Our goal is to model how Uber works at a small scale — drivers, riders, and rides using classes and methods.

I have written tests to guide you through the project. Please do not put your files inside the tests folder.

Learning Objectives

By the end of this project, you should be able to:

• Create and use classes and objects in Python.
• Define attributes and methods cleanly.
• Model relationships between objects (composition).
• Write and pass unit tests that validate program behavior.

Core Classes

Class	Purpose
Driver	Represents a driver with a name, car model, and ride history.
Rider	Represents a user who can request rides and rate drivers.
Ride	Represents a single trip connecting a driver and rider.
Uber	Manages drivers, riders, and rides (like a dispatcher).

Stages

Stage 1 - Drivers and Riders

• Implement Driver and Rider classes.
• Each should have a few attributes (e.g. name, car model, ride history).
• Implement __str__() or __repr__() for readable output.
• ✅ Tests will check creation and default values.

---

Stage 2 - Rides

• Implement a Ride class with attributes:
  • driver
  • rider
  • distance (float, km)
  • cost (calculated via RATE_PER_KM)
  • status ("requested", "in_progress", "completed")
• Implement methods:
  • start_ride()
  • complete_ride()
• ✅ Tests will check status transitions and cost correctness.

---

Stage 3 - Uber App (Dispatcher)

• Create an Uber class that:
  • Keeps a list of available drivers.
  • Assigns drivers to rides.
  • Manages active and completed rides.
• Prevent busy drivers from being reassigned.
• ✅ Tests will check correct assignment and driver availability reset.

---

Stage 4 - Ratings (Optional Extension)

• Riders can rate drivers (1–5 stars) after a ride completes.
• Drivers keep a record of ratings and an average score.
• ✅ Tests will verify correct average calculation.

Testing

All tests are written using unittest.

To run them:

python -m unittest tests/test_blah.py
