## Kết luận

Với những thông tin này, bạn có thể hiểu được **các biến môi trường là gì** và **cách sử dụng chúng trong Python**.

Bạn có thể đọc thêm về chúng tại <a href="https://en.wikipedia.org/wiki/Environment_variable" class="external-link" target="_blank">Wikipedia cho Biến môi trường</a>.

## Podsumowanie

* Zaimportuj `FastAPI`.
* Stwórz instancję `app`.
* Dodaj **dekorator operacji na ścieżce** (taki jak `@app.get("/")`).
* Napisz **funkcję obsługującą ścieżkę** (taką jak `def root(): ...` powyżej).
