Now let's say that you want to add a translation for the section [Features](features.md){.internal-link target=_blank}.

* Copy the file at:

```
docs/en/docs/features.md
```

* Paste it in exactly the same location but for the language you want to translate, e.g.:

```
docs/es/docs/features.md
```

!!! tip

* You can ask them to provide a <a href="https://stackoverflow.com/help/minimal-reproducible-example" class="external-link" target="_blank">minimal, reproducible, example</a>, that you can **copy-paste** and run locally to see the same error or behavior they are seeing, or to understand their use case better.

    ```Python hl_lines="2  5-8  11"
    {!> ../../../docs_src/settings/tutorial001_pv1.py!}
    ```

!!! tip "Tipp"
    Für ein schnelles Copy-and-paste verwenden Sie nicht dieses Beispiel, sondern das letzte unten.

    That's because it is using the same name as in the OpenAPI spec. So that if you need to investigate more about any of these security schemes you can just copy and paste it to find more information about it.

The `oauth2_scheme` variable is an instance of `OAuth2PasswordBearer`, but it is also a "callable".

It could be called as:

```Python
oauth2_scheme(some, parameters)

```

But right at the moment Python compares the first `j` in `johndoe` to the first `s` in `stanleyjobson`, it will return `False`, because it already knows that those two strings are not the same, thinking that "there's no need to waste more computation comparing the rest of the letters". And your application will say "Incorrect username or password".

But then the attackers try with username `stanleyjobsox` and password `love123`.

    ```Python hl_lines="2  5-8  11"
    {!> ../../../docs_src/settings/tutorial001_pv1.py!}
    ```

!!! tip
    If you want something quick to copy and paste, don't use this example, use the last one below.
