Eis a formatação de datas, permitindo que o usuário inclusive digite com trailing zeros:
class Date:
def __init__(self, day, month, year):
self.day = int(day)
self.month = int(month)
self.year = int(year)
def formatted_date(self):
return f"{self.day:02d}/{self.month:02d}/{self.year:4d}"
date_obj = Date(10, 9, 2023)
print(date_obj.formatted_date(), "\n")
date_obj_2 = Date(11, "03", 2020)
print(date_obj_2.formatted_date())Na sequência se pode usar esta formatação:
from dates import Date
class Account:
def __init__(self, number, holder, balance, limit=1000):
self.number = number
self.holder = holder
self.balance = balance
self.limit = limit
