For those that wish to use another language

It is possible though very difficult for a couple of the problems - see the comments on this page (some references to spoilers so dont go visiting if that bothers you) :

One guy implemented Python specific libraries in his language of choice (Lua) and has got as far as level 17 without using Python at all.

Have fun!

I was using many languages and only a couple of times Python.

I am using VBS for all most of the tasks, Java for networking, C# for file manipulation and occasionally C/C++, VB, Perl and some wide spread tools (GIMP, SoundForge etc.)
I tryed to not use Python at all but the picke level forced me so. I am doing this for fun and not for Python... is just another way to spend time at work .
