Following are the pros/Advantages and cons/disadvantage of Lua vs Python

• Lua is off-the-charts portable. It's by FAR the most portable language I've ever seen, maybe even the most portable program.
• What I mean by this isn't that Lua programs are portable (they're not, compared to Java), but Lua itself is.
• Just recently I built Lua on an IBM iSeries, with zero changes to the source code, I just compiled each Lua source ʸle with the IBM ILE C compiler.
• Compare that to getting say, Python BUILDING on some unknown UNIX, let alone a completely different OS like IBM i (OS/400).
• Lua is very simple, easy to PORT to a new platform, easy to integrate with C on that platform. It's a nice enough language, but nothing special, but it's portability is special.
• If the platform has an ANSI C compiler (and they pretty much all do, I can only think of a couple that do not), then you can almost CERTAINLY build Lua, that's very cool indeed.
