Solution

To answer the question, step by step:

  1. The first line creates a list called "a" with the elements [1, 2, 3, 4].
  2. The second line appends the number 5 to the list "a", resulting in the list [1, 2, 3, 4, 5].
  3. The third line uses the len() function to determine the length of the list "a", which is now 5.

Therefore, the final line of code, len(a), will print the value 5.
