LUA was originally designed as a configuration file language, and it really excels at that. LUA does not have many modules like Python does, but it provides a very simple and powerful table mechanism that is very easy to interface to and from c/c++ code. Therefore, anything you can write in c/c++ can be imported as a module into LUA.
I use LUA because the interpreter is small and easy to embed. There are a number of libraries out there to aid in embedding LUA, but I find they are not really needed.
The LUA interpreter’s code is very easy to hack, too, which is nice because I needed to adapt LUA’s script loading mechanism to my engine’s custom file i/o mechanism. Took me twenty minutes.
I have used both Python and LUA. My personal preference is that LUA is better for embedded scripting and Python is better for stand-alone scripting. I really like LUA’s syntax, too.

Python or Lua

Is there a list of commercial games that use ''standard'' scripting languages (say Lua or Python) and what language they used?
Blade: Edge of Darkness (aka Severence) was made with python for everything game related and its engine was done in C. Neverwinter Nights used Lua for its scripted levels. The Bigworld engine uses Python for most of its game and server related stuff.
Lua benefits:
1. Lightweight.
2. Easy to embed in a C++ project.
3. Significantly faster "out of the box," without relying on machine code generating extensions (like Psyco for Python).
Python benefits:
1. Richer language.
2. More predictable in terms of performance, because of reference counting over true garbage collection.
3. Much larger standard libraries.
4. Psyco compiler, if you need it.

The big advantage of python is that it is used a lot in the world : you find books, tutorials, libs, debuggers, ...
So perhaps Python has a better chance to stay than Lua...
But who knows ???
So, yeah, it''s going to last. It already has. (Not a comment on Lua''s long-term prospects!)
Plus with Python networking is a whole lot easier thanks to its huge number of libraries in that area, and that''s an asset not to be underestimated. Especially if you use Twisted Python =D

Did I mention "Don''t use tabs"?
What''s wrong with tabs? I have been using them for years in my code...no problems.

I prefer tabs over spaces because some people have different preferences for the number of spaces in indenting - with tabs they can set them to be equivalent to 2, 4, 8 spaces or whatever they want, and it won''t mess up your own preference.

Python interprets one tab character as being worth 4 spaces (IIRC), which may not match what your IDE displays. Which means that, if you mix tabs and spaces (which *look* the same unless you have an editor that does make whitespace visible), you can have code that appears to line up, but that python sees as unconsistently indented.
As for python's suitability to embedded platforms (in re: the PS2 commend), I believe there is at least one cell-phone that is (entirely?) scriptable in python.

I prefer lua because of the same reasons many people pointed out.
Someone mentioned python itself is very tiny without lib, that's not true. There is dll that has been installed to system directory and that's a good 800k.
The only concern I have about python vs lua is, with python you can always replace a python module with c++ without having to change any other part of the code or script. Does lua has the similar ability?
