Human: Podrías decirme como crear una interfaz sencilla (también conocida como gui) de una calculadora para el lenguaje de programación Python? intenta encontrar un código que sirva tanto para una calculadora corriente como para una calculadora científica, gracias.
Assistant: Claro que puedo decirte como crear la interfaz (GUI) en Python...
he encontrado algunos ejemplos que pueden ayudarte:

`simple.py`
```py
