As you say, results is a list of lists.

results[0] returns the first inner list. There could potentially be more 
than one, in which case results[1] would return the second one. Use 
len(results) to find out how many inner lists there are.

results[0][0] returns the first element of the first inner list.

results[0][1] returns the second element of the first inner list.
