Question

Please, help me to find a way how to resolve my problem. I have file structure like this

/j/
    lib/
         __init__.py
         ftpserver.py
    utils/
         __init__.py
         mogno.py
         My.py 
         __init__.py
         jftpd.py 

in ftpserver.py I have a class which is the base class for some class in My.py
I mean:

# ftpserver.py
class foo()
  ...

and My.py is something like this:

# My.py
class bar(foo)
 ...

what I want is to use all my modules in jftpd.py. But I cannot find a way to accomplish this. I am doing something like this:

# jftpd.py
import lib.ftpserver
import utils.My


***some usage of my classes***

And interpreter return me

NameError: name 'foo' is not defined

It could be a good solutions to use relative import in My.py:

from ..lib.ftpserver import foo

but this also is not working method because of relative import, which is not allowed in python. In spite of numerous examples of relative import i have found, I get an error:

ValueError: Attempted relative import in non-package

executing something like:

from ..lib.ftpserver import *

Can anybody help me?

Answer 1

Try from lib.ftpserver import foo. I can’t see any reason why that wouldn’t work. There’s no need for the .. element.

Make sure you import your original class where you define your inhereted one. For example:

from lib.ftpserver import foo

class AnyClasss(foo):
    foo
