I believe that this is separable into at least two questions: 1. Whats the deal about 2 and 3, as in where on the past-present-future do these sit 2. How to write software that is 2+3 compatible As for 1 its the much heat little light kind of discussion. I'll leave others to warm themselves and the planet As for 2 maybe we need a wiki page. (Or do we have one already?) Heres my largely ignoramus attempt at starting that: 1. print: Use print with (). Dont use funny 2 syntax 2. Always write strings with a u" prefix 3. Always use new style classes 4. Always use relative imports with explicit relative (ie use .)
