Post: RE: python machine learning model, macro precision...

I'm afraid that you don't give enough information for me to give you any more help. If your assignment doesn't say anything more, you surely have courses you can refer to.

Post: RE: How to generate the list I want?

Yeah it works. But I made it by hand in the end, the list I needed was just twice as big. But seriously, we need a module for that? I really have to read a whole manual just to make a simple list... A...

@DeaD_EyE: You think there is more to it than the fact that the file is written with mixed encodings making it ultra hard to process via python? I spent one hour after my last post trying to force enc...
