call packages and modules in python

Question

I am trying to call a package and a module but it throws an error.

the modules are

from DB_Manager* import
from Operate_System.OS_Resolution import*

but it generates the following error when trying to call it.

I don't know if the reason for the error is because the call is being made from a module that is in a subpackage to a module that is in a package, that is, if there is a problem trying to call a module of a lower level than a module of Upper level.

I appreciate your help.
