How to read tables?

I'm having some hard time trying to understand how to read the output of the peripheral API, like peripheral.getNames().

The output given by the computer is always something like

table: 2ed2cd7e

Yep, I don't know much about Lua.

So, when you get the table, you can iterate through it to see its contents. Try doing this:

local names = peripheral.getNames()
print("names contains:")
for k, v in pairs(names) do
  print(tostring(k)..": "..tostring(v))
end

That will let you see what's inside it.

Oh! I didn't know you had the for in loop in Lua. Cool!
