Esto significa:

* La variable `prices` es un `dict`:
    * Los keys de este `dict` son de tipo `str` (Digamos que son el nombre de cada ítem).
    * Los valores de este `dict` son de tipo `float` (Digamos que son el precio de cada ítem).

### Clases como tipos

También puedes declarar una clase como el tipo de una variable.

Digamos que tienes una clase `Person`con un nombre:

   * doesn't include framing overhead. If compression is enabled, uncompressed messages size
   * is used to calculate this value. It also doesn't include any bytes buffered by the operating
   * system or network intermediaries. This method returns 0 if no messages are waiting in the
   * queue. If may return a nonzero value after the web socket has been canceled; this indicates
   * that enqueued messages were not transmitted.
