使用子模块时的 Python 导入问题

Question

I have a directory structure as shown below:

--root
    --common
        util.py
    --submodule
        --common
            util.py
        --code
            a.py
        run.py
    main.py

a.py

from common.util import test_config

main.py

import submodule.a

a.py is importing some code from common module of the submodule. I have added this submodule in root project. the submodule itself works fine when run independently.

When I import a.py in main.py it starts to pick up code from root projects common code instead of the submodule project.

ImportError: cannot import name 'test_config'

I have tried adding sys.path in a.py to force import submodule code but it is not working.

a.py

currentdir = os.path.dirname(os.path.abspath(inspect.getfile(inspect.currentframe())))
parentdir = os.path.dirname(currentdir)
sys.path.insert(0, parentdir) 

from common.util import test_config

Any help is appreciated

Your code in a.py should either use a relative import:

from .common.util import test_config

...or a full import path:

from submodule.common.util import test_config
