From PEP 328, http://www.python.org/dev/peps/pep-0328/#rationale-for-relative-imports you should actually avoid naming a python module starting with a "dot" because it means relative imports in Python.
If you really insist on doing so, you can but you will have to use the imp module.
Example usage:-

A friend and I have been playing around with pygame some and came across this tutorial for building games using pygame. We really liked how it broke out the game into a model-view-controller system with events as a go-between, but the code makes heavy use of isinstance checks for the event system.
Example:

We seem to have a tradition of using the Homestar Runner character 'Trogdor the Burninator' to request tag deletion.
I thought we could use crisper images, so I made my own. >:)

The above were made using a Trogdor reference from an unknown person on the internet, which has some inaccuracies.... |
First, you will need the Color class from Gdk and the Gtk class:
from gi.repository import Gtk
from gi.repository.Gdk import Color
Then, in your handler, change the foreground color of the text field:
COLOR_INVALID = Color(50000, 0, 0) // A dark red color
text_field.modify_fg(Gtk.StateFlags.NORMAL, COLOR_INVALID)
If ... |
Currently I have the following code:

field_values = db.StringListProperty(indexed=False)
field_scores = db.ListProperty(int, indexed=False)
def fields_add(user_key_name, field_name, field_value, field_score):
user = User.get(user_k... |

Because I added "Add Key" yesterday, today I wanted to be symmetrical, so I added "delete keys". This turned out to be much more work. First, I ended up creating another quickly.prompt, and then I had to dive into the internals of CouchGrid, and also do some hair raising mucking with desktop couch.

Past midnight and maybe someone has an idea how to tackle a problem of mine. I want to count the number of adjacent cells (which means the number of array fields with other values eg. zeroes in the vicinity of array values) as sum for each valid value!.
