如何从兄弟目录导入Python脚本？

Here is the directory structure:

这是目录结构:

parent_dir/
    foo_dir/
        foo.py
    bar_dir/
        bar.py

How do I import bar.py into foo.py?

如何将bar.py导入foo.py?

2 个解决方案

#1

If all occurring directories are Python packages, i.e. they all contain __init__.py, then you can use

如果所有发生的目录都是Python包,即它们都包含__init__.py,那么您可以使用

from ..bar_dir import bar

If the directories aren't Python packages, you can do this by messing around with sys.path, but you shouldn't.

如果这些目录不是Python包,你可以通过搞乱sys.path来实现,但你不应该这样做。

#2

You can use the sys and os modules for generalized imports. In foo.py start with the lines

您可以使用sys和os模块进行通用导入。在foo.py中以行开头

import sys
import os
sys.path.append(os.path.abspath('../bar_dir'))
import bar
