## FastAPI App with Tags

In many cases your FastAPI app will be bigger, and you will probably use tags to separate different groups of *path operations*.

For example, you could have a section for **items** and another section for **users**, and they could be separated by tags:

//// tab | Python 3.9+

```Python hl_lines="21  26  34"
{!> ../../docs_src/generate_clients/tutorial002_py39.py!}
```
