  • Ready to use TSP library

    - by Max
    Hi, I'm currently doing a project that requires some fast TSP solving (about 50-100 nodes in 2 seconds). There are a lots of approximation algorithms out there, but I don't have time nor will to analyze them and code them myself. Are there any free libraries that can solve TSP problem (approximation will do too)? Something like sortedNodes = solveTspPrettyPlease(nodes, 2sec) would be just great. Thanks in advance.

  • Making Noise with Python

    - by Elliot
    I am trying to get python to make noise when certain things happen. Preferably, i would like to play music of some kind, however some kind of distinctive beeping would be sufficient, like an electronic timer going off. I have thus far only been able to make the system speaker chime using pywin32's Beep, however this simply does not have the volume for my application. Any ideas on how I can do this?

  • Python shortcuts

    - by lyrae
    Python is filled with little neat shortcuts. For example: self.data = map(lambda x: list(x), data) and (although not so pretty) tuple(t[0] for t in self.result if t[0] != 'mysql' and t[0] != 'information_schema') among countless others. In the irc channel, they said "too many to know them all". I think we should list some here, as i love using these shortcuts to shorten & refctor my code. I'm sure this would benefit many.

  • installing opencv for python issues

    - by vlad
    I'm running OS X Leopard. I followed this site to install it. Trying to run any demo script, I now get "No module named opencv.cv", which is obviously stopping me from doing any programming. I am running python 2.5.1 (yes, I know it's kind of old). Why would this be, and how can I solve it? Thanks
