Python, the open source programming language that sees itself as an alternative to Java and brags about being used at Google, Industrial Light & Magic and NASA, will be having its PyCon user conference March 14-16 at the Crowne Plaza Chicago O'Hare Hotel. Python creator Guido van Rossum, now working for Google, is supposed to present the next-generation Python 3000 in the works for two years. See http://us.python.org.
