[Python] Errore all'avvio di python.

[Marco Giusti]

Buongiorno Gabriele,
   sembra che il file pyreadline/py3k_compat.py della libreria pyreadline
non sia aggiornato dal 2012. Callable fa ora parte del package
collections.abc, non collections. Disinstalla pyreadline e dovresti
essere in grado di lanciare l'interprete Python.
