Python, import package module when class inherit abstract class

Question

bank
    __init__.py
    Account.py
    SavingAccount.py
main.py

The SavingAccount class is inherit from Account(abstract class). When main.py import SavingAccount as below:

from bank.SavingAccount import SavingAccount

It appear "No module named 'Account'". Could someone know how to solve it?

The complete error code in output window as below:

Traceback (most recent call last):
  File "main.py", line 5, in <module>
    from bank.SavingAccount import SavingAccount
  File "\bank\SavingAccount.py", line 1, in <module>
    from Account import Account
ModuleNotFoundError: No module named 'Account'

Acccount.py

from abc import ABCMeta,abstractmethod
class Account(metaclass=ABCMeta):
    _id = 0
    _name = ''
    _balance = 0
    __next = 0

    def __init__(self,name,initBal = 1000):
        self._name=name;
        self._balance = initBal

SavingAccount.py

from Account import Account
class SavingAccount(Account):
    _interestRate = 0

    def __init__(self,name,initBal=0):
        super(SavingAccount,self).__init__(name,initBal)

    @classmethod
    def interestRate(cls):
        _interestRate = 0

    @classmethod
    def interestRate(cls,rate):
        cls._interestRate = rate

Python 2 or Python 3? If you want to import sibling submodules of the same package, you should do it either by absolute import or by *explicit* relative import. — user2357112, Aug 29 '17 at 02:11

You should change

from Account import Account

to

from .Account import Account

The latter relative import approach is recommended inside a package.
