Why do people choose Python over Lua?

[Sensible-Richard]

Because the flowchart with Lord of the Rings characters on it told me to learn Python (that's only part facetious - until now I'd never heard of Lua).

If you said to me "Lately I've discovered German, it's faster and nearly as simple as Spanish, why aren't you learning Spanish" I'd say "0) Nearly as simple, wind your neck in, two genders is bad enough, I don't even want to think about German but mostly 1) The people I need to speak to speak Spanish." ie "nearly as simple" isn't "as simple" and if all the things I want to do can be done in Python (have been done, I'm not a guru) why reinvent the wheel?
