Now, i get additional dir in the path: '/home/sneetsher/Desktop/sandbox/alfanous-snap'

Full sys.path:

['/snap/alfanous/x7/usr/bin',
 '/snap/alfanous/x7/usr/lib/python2.7/site-packages',
 '/snap/alfanous/x7/usr/lib/python2.7/dist-packages',

 '/snap/alfanous/x7/usr/lib/python2.7/lib-old',
 '/snap/alfanous/x7/usr/lib/python2.7/lib-dynload']

When I run my app, I get this error message:

    for entry in os.listdir(path_item):
