## Example upgrade { #example-upgrade }

Now modify the file `main.py` to receive a body from a `PUT` request.

Declare the body using standard Python types, thanks to Pydantic.

```Python hl_lines="4  9-12  25-27"

    /// note

    The `--no-cache-dir` is only related to `pip`, it has nothing to do with Docker or containers.

    ///

    The `--upgrade` option tells `pip` to upgrade the packages if they are already installed.

    Because the previous step copying the file could be detected by the **Docker cache**, this step will also **use the Docker cache** when available.
