Hi Python gurus,
Can anyone please give some examples / applications of the use of the following advanced (advanced to me, at least :-) features of Python :
1. lambda
2. nested functions - a little info was given by Danny in reply to my earlier post on local-static variables, but I would like more.
3. Thoughts on implementing Interfaces in Py - a la Java interfaces.
I am, and will be doing more, on reading the docs and googling for this, but would anyway appreciate inputs from those who know this stuff.
I have a specific reason for the above questions- apart from general interest, of course -> I am planning to write a game-playing program in Py which will have features somewhat AI - ish. I don't have any background in AI; nor much in functional programming. I do understand recursion though. I suspect that some of the above 3 points will help me to write my app in a better way. though not sure, of course. Hence the request for examples.
For all of the above 3 points, I'm interested in :
- code examples of their use
- in what way their use makes code simpler, or maybe makes code possible that could not be written otherwise ('possible' in practical terms - I'm - vaguely - aware of the fact that all languages are supposed to be theoretically 'Turing-equivalent' or some such term - but what I mean is that if something is going to take a huge amount more code in some other language, or jumping through hoops, then I don't call it practically equivalent).
Thanks !
Az
