Here\'s the structure I\'m working with:
directory/
script.py
subdir/
__init__.py
myclass01.py
I use this simple way:
import module or from module import function1, class1 in that directory.notice that the module is nothing but the name of your *.py file, without the extension part.
Here is a general example:
import sys
sys.path.append("/path/to/folder/")
import module # in that folder
In your case it could be something like this:
import sys
sys.path.append("subdir/")
import myclass01
# or
from myclass01 import func1, class1, class2 # .. etc
