[Tutor] problem running iptest on windows

Hi I just installed Ipython 0.9.1.win32 (and Python 2.5.1) under Windows XP. I added C:\Python25\Scripts to my path environment variable but nothing else. Out of curiosity, I then decided to try running the iptest script (after installing the nose code) but I keep getting import errors. Here

Re: [Tutor] list output -- float output

Thank you for the advice. Actually, what annoys me is that list textual output, either with print or str(), calls repr() for each item of the list, instead of str(). That's why I had these strange things with floats, as illustrated in my first post on the topic: class Seq(list): ''' se

Re: [Tutor] Classes and Databases

Sorry Alan, What u described below is exactly what i want to do.. if given x, y as two datatums and such that f(x) --> y, given y can we determine f or x? Assuming the x, y and f are stored in the database, then we can be able to write queries to search/extract for the f's that are responsible f
