Python language 3.7.3 : Filenotfounderror: [Errno 2] . .

Question

Good morning.

I have the following code in a class that works perfectly well when I print inside it. Now when access through another class file presents me error. Below demonstrate class that works :

import os 
class WspApplication:

ws_listdir = os.listdir('../application/controllers')

This class works when I print inside it.

It only shows the error below when I try to access it in another class:

ws_listdir = os.listdir('../application/controllers') Filenotfounderror: [Errno 2] No such file or directory: '.. /application/controllers'

Below follows the other class :

from syscore.wsp_application import WspApplication
class WspProtected:

def wsm_dir(ws_path):

    ws_root = WspApplication.ws_listdir
    if ws_path == ws_root:
        return 'Info. . .'.encode('utf-8')

You can disregard the path parameter in the analysis it works !
