For example, there's an official [Python Image](https://hub.docker.com/_/python).

And there are many other images for different things like databases, for example for:

* [PostgreSQL](https://hub.docker.com/_/postgres)
* [MySQL](https://hub.docker.com/_/mysql)
* [MongoDB](https://hub.docker.com/_/mongo)

That's why, as said in the official website:

> Requests is one of the most downloaded Python packages of all time

The way you use it is very simple. For example, to do a `GET` request, you would write:

```Python
response = requests.get("http://example.com/some/url")
```

The FastAPI counterpart API *path operation* could look like:

```Python hl_lines="1"
@app.get("/some/url")
def read_url():
