Pero ese archivo no existe, nuestras dependencias están en un archivo en `app/dependencies.py`.

Vou lhe contar um pouco mais sobre esses **conceitos** aqui, e espero que isso lhe dê a **intuição** necessária para decidir como implantar sua API em ambientes muito diferentes, possivelmente até mesmo em **futuros** ambientes que ainda não existem.

Ao considerar esses conceitos, você será capaz de **avaliar e projetar** a melhor maneira de implantar **suas próprias APIs**.
