Tengo dos archivos y uno de ellos es "money.py". En este archivo se almacena la cantidad total de dinero en la cuenta de mi usuario. Sin embargo, el problema es que actualmente no hay forma de distinguir entre dos usuarios y su dinero en mi programa, ya que solo almacena el valor entero de su monto total. También lo intenté escribiendo el nombre de usuario y luego la cantidad de dinero, pero descubrí que esto no funciona, ya que mezcla cadenas y números enteros. ¿Hay alguna manera de distinguir entre diferentes usuarios? Gracias.

Esta pregunta se habría planteado mejor en stackoverflow.
Mi sugerencia es almacenar sus saldos en un diccionario, por ejemplo, balances[user] = amounty usar el jsonmódulo para leerlo/escribirlo desde el archivo.
cargar:
with open("money.py", "r") as moneyfile:
balances = json.load(moneyfile)
ahorrar:
with open("money.py", "w") as moneyfile:
json.dump(balances, moneyfile)
nota: .pyes la extensión utilizada para el código fuente de Python; para almacenar datos se prefiere otra extensión, por ejemplo, .txto.dat
