Not a very godd idea to mess with the python path

A quick fix is to promote your my_scripts folder to be a python package,
by creating a python module (file) named __init__.py right in the
package directory. The content of __init__.py can be for instance
#!/usr/bin/env python
# -*- coding: Latin-1 -*-
"""
my_scripts package containing miscellaneous modules 
  PolyDraw
  ....
"""

To import from this package the syntax is
from my_scripts import PolyDraw
