Python包/模块导入

Question

I've gone through a lot of resources, but I simply cannot get this to work. I am trying to do an absolute import for some config files and library class files of my own, but the import fails. Here is a simple example:

└── import_test
    ├── __init__.py
    ├── config
    │   ├── __init__.py
    │   └── database.py
    └── services
        ├── __init__.py
        └── data.py

Here is the database.py

mysql = {'host':    'localhost',
         'user':    'root',
         'passwd':  'password',
         'db':      'db_name',
         'charset': 'utf8'}

and here is data.py

from import_test.config import database

When I run the data.py, I get this error.

ModuleNotFoundError: No module named 'import_test'

What am I doing wrong?

Thanks!
