really handy when you know what you want, but don't know how exactly e.g. how do I get a value into or out of a dictionary etc.
Also browsing other peoples python code helps. As pointed out by Syan – "I learnt stuff from looking at Ian's short-cut code, and I saw an alternative to using the filter() list utility function when I looked at bittorrent code... The pycommon code is also a good source for learning."
