类继承抽象类时导入包模块

Python, import package module when class inherit abstract class(类继承抽象类时导入包模块)

问题描述

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

SavingAccount类继承自Account(抽象类)。当main.py导入SavingAccount时如下所示：

来自银行。SavingAccount导入SavingAccount 它会显示"没有名为‘Account’的模块"。有没有人知道怎么解决它？

输出窗口中的完整错误代码如下：

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

Acccount t.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 t.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

推荐答案

您应该更改

from Account import Account

至

from .Account import Account

建议在包内使用后一种相对导入方法。
