También podrías usar `from starlette.templating import Jinja2Templates`.

**FastAPI** proporciona el mismo `starlette.templating` como `fastapi.templating`, solo como una conveniencia para ti, el desarrollador. Pero la mayoría de los responses disponibles vienen directamente de Starlette. Lo mismo con `Request` y `StaticFiles`.
