Python Puzzle #2

Here is the challenge #2. This one deserves more explanations.
Your team has to maintain a legacy project, and for various historical reasons, the project has not enough documentation. Features delivery is always a higher priority than the documentation update.
So, you decide it's time that every team member commits to read and improve the documentation.
The plan is to spend an hour every Monday, Wednesday and Friday to this task, each team member in turn.

you want a function, that given a start date and a number of weeks, will assign the team member to this maintenance.

Python Puzzle #1

I plan to publish a serie of Python puzzle, or challenges.
Mostly around data manipulation, they can be a great way to improve your python skills.
There is many ways to solve this, you can chose your style from:

• best performance 
• best readability 
• least lines of code 
• most obfuscated 

the goal is to pass the unit test(s).

import unittest


def dotted_to_dict(incoming):
    pass


class TestDottedToDict(unittest.TestCase):
    def setUp(self):
        self.dotted = [{'a': 1, 'b.e.f': 2, 'b.e.g': 9, 'c.a': 5, 'c.d': 10},
                       {'a': 6, 'b.f.f': 8, 'b.f.g': 0, 'c.a': None, 'c.d': 15},
        ]

        self.expected = [{'a': 1, 'b': {'e': {'f': 2, 'g': 9}}, 'c': {'a': 5, 'd': 10}},
                         {'a': 6, 'b': {'f': {'f': 8, 'g': 0}}, 'c': {'a': None, 'd': 15}},
        ]

    def testClasses(self):
        """
        """
        got = dotted_to_dict(self.dotted)
        self.assertEquals(got, self.expected)

Please comment if you feel the question is not clear enough.
Have fun!
