Find the closest relative

Hi I have three objects, all of them are instances of classes derived from a base class. Now, given one of the instance, I want to find the closest relative of the other two. How can I do this? This is how I implemented; I guess there must be elegant way to do this... def find_closest_relative(a,

No file from stdin

Hi, suppose a script of python is waiting for a file from the stdin and none is given. How can I make the script to stop and, for example, print an error message? Sorry for the n00b question and thanks -- http://mail.python.org/mailman/listinfo/python-list

need advice on building core code for python and PHP

All, I'm currently working with a small development company on a PHP application they already have. There are several processing tasks that could be scripted in Python and run in the background to modify a database, instead of the way they have it now, which waits for a webpage to return from proc

Reading (and writing?) audio file tags

I'd like to write some scripts to analyze and manipulate my music files. The files themselves are in MP3 and FLAC format (mostly MP3, but FLAC where I ripped original CDs and wanted a lossless format). I've no idea what form of tags are used in the files (ID3v1, ID3v2, OGG, APE, ...) I just used wh
