How to print the name of a key in a dictionary?
3 answers
✓ Accepted answer
Hey there!
The only method of getting the name of the key in the dictionary that I know of is using a for loop.
Example:
local items = {sword = 2, shield = 3}
for i,v in pairs(items) do
print(i)
end
However, this will not print in order as dictionaries don't have an order. So the output will either be
--sword
--shield
or
--shield
--sword
#Do
print(itens.sword) -- 2
Apologies for lack of elaborate answer.
You can print by using itens[Numberhere] , for example:
print(itens[1])
It would print 2 (or shield idk)
