folders

I have a python script that uses classes from a file next to my main.py named 'src'. These classes use images from the file 'img' next to main.py as well.

I'm writting the path as follows :

"img/myImage.gif"

When I run it from my python shell it works fine but I just can't run it using the command prompt (path not found).

I tried

"/img/myImage.gif" and "./img/myImage.gif"

and also moving my 'img' file to src, and to main.py's parent file but it doesn't work..

I'm out of ideas.. any assistance would be appreciated, Thanks,

This is what you need to do for you folder structure,

program
   main.py
   src
      __init__.py //empty py file
      classA
           __init__.py
           classA.py

      classB
           __init__.py
           classB.py

"../../img/myimage.gif"          // to use in classA.py file

More Explanation:

if your main.py is in 

    src
       main.py
    img
       myimage.gif

use this

"../img/myimage.gif"

if your folder structure is (moving img inside src)

-src
    main.py
   -img
       myimage.gif

you need to use like below

"img/myimage.gif"

  • thanks for this clarification, I think that I also have to add the path of my project to the PYTHONPATH ? – vbuzze May 25 '16 at 08:28
  • wel, i think so we should. main.py and classA.py are not in same level, and Python cant able to figure out if main.py importing classA.py module!! let me know if i m wrong. do accept this ans if this resolved your problem :) – Arun G May 25 '16 at 08:30
  • try doing this in main.py, import os, sys PROJECT_PATH = os.path.abspath(os.path.dirname(__file__)) sys.path.append(PROJECT_PATH) sys.path.append(os.path.join(PROJECT_PATH, 'classA')) – Arun G May 25 '16 at 08:39
  • my classes are found because they are imported in my main as follows: from src.classA.ClassA import ClassA but within these classes I can't load my images (from 'img') – vbuzze May 25 '16 at 08:42
  • I tried to add all this in main.py (changing 'file' with the path of my project and changing 'classA' to 'img') but it doesn't solve the problem – vbuzze May 25 '16 at 08:51
  • you have two options,1. in classA module refer "myimage" with absolute path. 2. under folder "src" create (__init__.py) and under classA and classB folder create "__init__.py" (this might solve ur problem) not able mention "_" underscore inthe comment ( underscore-underscore-init-underscore-underscore-.py) – Arun G May 25 '16 at 09:00
  • I do have __init__.py within every folders – vbuzze May 25 '16 at 09:03
  • create file (init empty file) reference http://stackoverflow.com/questions/448271/what-is-init-py-for – Arun G May 25 '16 at 09:04
  • It seems to work with absolute paths but I'd like to avoid it if possible – vbuzze May 25 '16 at 09:08
  • Relative paths are relative to the user's current directory, not your script's (though there are ways to achieve the latter, too). – tripleee May 25 '16 at 17:04
