Python import module issue on ubuntu

Question

I have two python files :

DatabaseFunctions.py and tele_bot.py .

On windows side I'm importing DatabaseFunctions.py module inside tele_bot.py and everything is fine .

import code line : from .DatabaseFunctions import *

when I upload my files in ubuntu server side , I'm getting this error :

SystemError: Parent module '' not loaded, cannot perform relative import

I also tried from appname.DatabaseFunction import * then I got this :

No module named 'appname'

Here is my directory structure :

firstBot/
      __init__.py
      DatabaseFunctions.py
      tele_bot.py

anyone can help ?

Do you have an `__init__.py` in the imported module directory? Is the path correct? — ggdx, Sep 27 '18 at 07:43
Can you please add your directory structure to your question? — toti08, Sep 27 '18 at 07:45
Did you try removing the `.` from the line `from .DatabaseFunctions import *`? — toti08, Sep 27 '18 at 07:54

Did you tried to use

import firstBot.DatabaseFunctions

This should work on windows or linux. But i would recommend to use lowercase file- and foldernames like firstbot/database_functions.py, so it may look like that:

from firstbot.database_functions import *

this will raise this error : ' ImportError: No module named 'firstBot' ' – Mehdi bahmanpour Sep 27 '18 at 09:02
Do you have the parent directory in your `$PYTHONPATH` variable? – norok2 Sep 27 '18 at 09:23

@norok2 ok thanks , where can i find this variable and add my directory ? – Mehdi bahmanpour Sep 27 '18 at 09:45
@Mehdibmp something like `sys.path.append()` should do the trick. – toti08 Sep 27 '18 at 09:50
