Parenthesis don't always make a tuple (and in fact aren't needed to make
them)

('first') is just the string value 'first', inside a set of parenthesis
to possible affect order of operations.

For 1 element tuples, you need a trailing comma, like ('first,) and in
many places it also could be just 'first',

just like your first example could be just for n in 'first', 'second':
