Hi, I am studying some examples in a tutorial where there are a lot of leading >>> characters and ellipsis in the text. This makes it hard to cut and paste into the IPython interpreter since it doesn't like these strings.

I am having a problem figuring out how to solve this problem the Django and (probably) the Python way. I am sending a hash to a template that contains the following values {'date': '2009-12-30', 'locations': [{u'lat': 43.514000000000003, u'lng': -79.844032999999996, u'place': u'1053 Bowring Cres, Milton, ON L9T, CA', u'description': u'...

I have always regretted certain design decisions I made since they prevented the application from being 'testable'. I read through the book and while some of it looks alien, I felt that I could manage it an...

I have two parts of a procedure that belong inside a main header. Something like step 2 has parts 2.1 and parts 2.2. Commenting so far I have so...
