It's time to wrap things up! First, let's have a quick review of what we've learned:

1. Tuples may or may not be defined with parentheses, but they require commas:

   sample_tuple = 1, 2, 3
   another_tuple = (1, 2, 3)
   

2. To access an element or a few of them, use square brackets:

   sample_tuple[1]
   sample_tuple[:2]
   

3. To iterate over a tuple, use a for loop:

   for item in sample_tuple:

4. To check if a tuple contains an element, use the in operator:

   if item in sample_tuple:

5. You can unpack a tuple into a group of variables:

   number_one, number_two, number_three = sample_tuple

6. You can return tuples from functions and precede a function parameter with an asterisk (*) if you want to allow a varying number of arguments:

   def function_name(*args):

All right, how about a short quiz now?
