Python - how do i load my custom class methods from a root directory?

Question

How do import my class from a specific directory (in my case root directory i want to keep it).

So, i have following directory map, now i need to load the class parsePresets from myglobal.py file, which is located in root directory: /var/tmp/mypython directory.

but, i want to import that from class/methods from my new module: /var/tmp/mypython/media/test.py with:

from myglobal import parsePresets

but i am getting:

    from myglobal import parsePresets
ImportError: No module named myglobal

i also have init.py in root directory and in the media directory.

$ cd /var/tmp/mypython; tree

You can add sys.path.append(/var/tmp/mypython/media/) to your script.

EDIT:

$ cat >> /var/tmp/mypython/stackoverflow.py <<\EOF
import sys
sys.path.append("/var/tmp/mypython/")
from myglobal import parsePresets
EOF
$ python /var/tmp/mypython/stackoverflow.py

or with NINJA-IDE

Running: /var/tmp/mypython/media/stackoverflow.py (Wed Dec 11 13:37:25 2013)



Execution Successful!

Use relative imports

from ..myglobal import parsePresets

The extra periods . take you "out" a level in your hierarchy.
