Online Debugging

[Yansky]

I'm trying to debug a script on my server and it's taking forever
using print to find the error. I've tried to use the debugging
examples on this page http://webpython.codepoint.net/debugging but
they don't seem to be working for me.

Is there an easier/better way to debug online scripts? I was hoping
there might be something similar to php where it gives some error info
and the line code.

Cheers.
