    CharSource concatenated = CharSource.concat(cycle);

    String expected = "abcdabcd";

    // read the first 8 chars manually, since there's no equivalent to ByteSource.slice
    // TODO(cgdecker): Add CharSource.slice?
    StringBuilder builder = new StringBuilder();

E, então, adicionando o argumento de palavra-chave extra `hashed_password=hashed_password`, como em:

```Python
UserInDB(**user_in.model_dump(), hashed_password=hashed_password)
```

...acaba sendo como:

```Python
UserInDB(
    username = user_dict["username"],
    password = user_dict["password"],
    email = user_dict["email"],
    full_name = user_dict["full_name"],

Dessa forma, ao digitar `python` no terminal, o sistema encontrará o programa Python em `/opt/custompython/bin` (último diretório) e o utilizará.

//// tab | Windows

Digamos que você instala o Python e ele acaba em um diretório `C:\opt\custompython\bin`.

Se você disser sim para atualizar a variável de ambiente `PATH`, o instalador adicionará `C:\opt\custompython\bin` à variável de ambiente `PATH`.
