📘 Assignment: Day 1 – Foundation and First Steps with FastAPI

🎯 Objective

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

• Set up a FastAPI project environment
• Create and run a basic FastAPI application
• Understand and explore FastAPI’s automatic documentation features

---

📝 Tasks

1. Environment Setup

• Create a new project folder named fastapi_day1
• Set up a virtual environment and activate it
• Install FastAPI and Uvicorn:

  pip install fastapi uvicorn

2. Create Your First FastAPI App

• Create a file named main.py

• Implement a basic FastAPI app with one route:

  from fastapi import FastAPI
  
  app = FastAPI()
  
  @app.get("/")
  def read_root():
      return {"message": "Hello, FastAPI!"}

3. Run and Explore

• Run the app using:

  uvicorn main:app --reload

• Open your browser and explore:
  • Swagger UI at http://127.0.0.1:8000/docs
  • ReDoc at http://127.0.0.1:8000/redoc

4. Add Another Endpoint

• Add a new route /hello/{name} that returns a personalized greeting using a path parameter.

5. Reflection Questions

Write short answers (2–3 sentences each):

• What are the key benefits of using FastAPI over Flask or Django for APIs?
• How does FastAPI use Python type hints to improve development?
• What did you find most interesting or surprising about the auto-generated docs?
