Now you're all set up to start coding with Python using VS Code!

1. create virtual env python3 -m venv venv
2. Activate: source venv/bin/activate
3. Install FastAPI pip install "fastapi[all]"
4. Check all packages installed pip freeze
5. Run the live server: uvicorn main:app --reload
6. Main.py is the entry point of our application
7. Open http://127.0.0.1:8000/
8. Interactive API docs Now go to http://127.0.0.1:8000/docs
9. Alternative API docs: http://127.0.0.1:8000/redoc
10. Check schema http://127.0.0.1:8000/openapi.json

Understanding FASTAPI

1. Below is route, A "path" / is also commonly called an "endpoint" or a "route".
2. The @app.get("/") tells FastAPI that the function right below is in charge of handling requests that go to:
3. Instance app = FastAPI()
4. Decorator @app.get("/")
5. http method is @app.get("/")
6. Function name async def root(): you can chnage root to a descriptive function name to whatever, like login_user

app = FastAPI()

@app.get("/")
async def root():
    return {"message": "Hello Welcome To Python3"}
