如何从同级文件夹中导入Python模块? [英] How to import a Python module from a sibling folder?

问题描述

我经历了许多关于Python的相对导入问题，但我无法理解该问题/无法正常工作.

I have gone through many Python relative import questions but I can't understand the issue/get it to work.

我的目录结构是:

Driver.py

A/
      Account.py
      __init__.py

B/
      Test.py
      __init__.py

Driver.py

from B import Test

Account.py

class Account:
def __init__(self):
    self.money = 0

Test.py

from ..A import Account

当我尝试运行时:

python Driver.py

我得到了错误

Traceback (most recent call last):

from B import Test

File "B/Test.py", line 1, in <module> from ..A import Account

ValueError: Attempted relative import beyond toplevel package

推荐答案

之所以发生这种情况，是因为就Python而言，A和B是独立的，不相关的软件包.

This is happening because A and B are independent, unrelated, packages as far as Python is concerned.

在与Driver.py相同的目录中创建一个__init__.py，所有内容均应按预期工作.

Create a __init__.py in the same directory as Driver.py and everything should work as expected.
