## Include the same router multiple times with different `prefix` { #include-the-same-router-multiple-times-with-different-prefix }

You can also use `.include_router()` multiple times with the *same* router using different prefixes.

## Використання тієї ж залежності кілька разів { #using-the-same-dependency-multiple-times }

Якщо одна з ваших залежностей оголошена кілька разів для однієї операції шляху, наприклад, кілька залежностей мають спільну підзалежність, FastAPI знатиме, що цю підзалежність потрібно викликати лише один раз на запит.

Las variables de entorno pueden ser útiles para manejar **configuraciones** de aplicaciones, como parte de la **instalación** de Python, etc.
