Run Locally (Validate your script functionality):
    Create a virtualenv and install ():
        cd C:\Users\win11-pc\PycharmProjects\FastAPISample

        python -m venv .venv
        source .venv/bin/activate        # on PowerShell: .\.venv\Scripts\Activate.ps1
        pip install -r requirements.txt

        #uvicorn main:app --reload
    Start Server
        #uvicorn main:app --reload
        uvicorn main:app --host 127.0.0.1 --port 8000
        uvicorn main:app --host 0.0.0.0 --port 8000 --reload
        note:   The --reload flag tells Uvicorn to automatically restart whenever you edit your Python files.
                This is safe for local development (not for production).
