Practising Python skills

I recently followed 2 courses from Udacity:

• CS101: Building a search engine
• CS373: Programming a robotic car

Both courses used Python as programming language and I have to admit that it has a low-barrier to get started. I'm currently thinking about a programming assignment which can be solved in a number of ways:

• Dynamic programming
• A*
  
• ...

For the time being here is some experimental code that will be heavily due to changes ;-)
