You create tuples with parentheses instead of square brackets: python coordinates = (10, 20) colors = ("red", "green", "blue") mixed = (1, "hello", 3.14, True) An empty tuple uses empty parentheses: empty = ().
A tuple with one element needs a trailing comma: single = (42,). Without that comma, Python sees (42) as just the number in parentheses, not a tuple. You can also use the tuple() constructor to convert other sequences: tuple([1, 2, 3]) creates (1, 2, 3).
