### Crea una *path operation* para probarlo { #create-a-path-operation-to-test-it }

Ahora, para poder probar que todo funciona, crea una *path operation*:

{* ../../docs_src/custom_docs_ui/tutorial001_py39.py hl[36:38] *}

### Pruébalo { #test-it }

### Aplicación de nivel superior { #top-level-application }

Primero, crea la aplicación principal de nivel superior de **FastAPI**, y sus *path operations*:

{* ../../docs_src/sub_applications/tutorial001_py39.py hl[3, 6:8] *}

### Sub-aplicación { #sub-application }

Luego, crea tu sub-aplicación, y sus *path operations*.
