30.1 easy_ATM_GUI_OOP.py

# -*- coding: utf-8 -*-

#  Ejercicio sencillo GUI y OOP

# Requisitos:
# 1.  No habrá login.  Simplemente cree las opciones de un ATM
# 2.  Un ATM da muchos mensajes al usuario.  Agregue los mensajes a donde pertenen.
# 3.  Vamos a mantenerlo muy sencillo.  Los retiros y consignaciones serán de 10$
# 4.  Conecte los botones con las funciones correspondientes para que el ATM funcione correctamente

# Quiere reto?
# Reto 1.  Modifique su código para que no pueda retirar más de su balance.  Use el mensaje FALLO. 
# Reto 2.  Modifique su código para que tan pronto ejecutemos el ATM, veamos un mensaje de bienvenida. 
#          Use el mensaje 'welcoming_message'.
