[Question][String?/Numbers]Combining strings/numbers from a table to a single variable

As the title says, I am trying to take random letters and numbers from a table which is randomly generated, and make them all into a single variable.

I have been going through the http://lua-users.org/wiki/ for about an hour now looking for such a function, and this is my question, does this exist? or do we have to come up with some really smart way of combining them?

*EDIT*

Found it. Just by chance, table.concat(table, separator)

so if you did something like

tableToJoin = {1,2,3,4,5,6,7}

joined = table.concat(tableToJoin, ",")

It would create it exactly how it is in the table, but if you were to change the separator to like "l" then there would be a l between each table item in the variable, so like 1l2l3l4l5l6l7

tostring should do what you need if you are dealing with elements individually, otherwise this works if you just want the whole table in the variable

t = {1,2,3,4,"5 6 7 8 9"}
print(table.concat(t, ', '))

that will output

1, 2, 3, 4, 5 6 7 8 9

Yeah, I got it probably as you posted that, Its intended as a randomly generated cipher for an encryption function

fair enough. just on a side note this code

t = {1,2,3,4,"5 6 7 8 9", someKey = 5, ['anotherKey'] = 'aValue'}
print(table.concat(t, ' '))

will still only output

1, 2, 3, 4, 5 6 7 8 9

it doesn't do key/values…

Thats sort of implied, because of how the tables work with that, it doesn't print the table key if you just print() it

just making sure you realised, not everyone does, and not everyone knows how it works in the backend. so it could be helpful to anyone else reading the thread.
