Exercise

A brief introduction to tuples

Alongside learning about functions, you've also learned about tuples! Here, you will practice what you've learned about tuples: how to construct, unpack, and access tuple elements. Recall how Hugo unpacked the tuple even_nums in the video:

a, b, c = even_nums

A three-element tuple named nums has been preloaded for this exercise. Before completing the script, perform the following:

  • Print out the value of nums in the IPython shell. Note the elements in the tuple.
  • In the IPython shell, try to change the first element of nums to the value 2 by doing an assignment: nums[0] = 2. What happens?

Instructions

  • Unpack nums to the variables num1, num2, and num3.
  • Construct a new tuple, even_nums composed of the same elements in nums, but with the 1st element replaced with the value, 2.
