AO1 – Knowledge & Understanding

1. list_literals.py

   Write a program that creates a Python list containing exactly 5 integers. Print the list to check its values.

2. two_d_list.py

   Create a 2-D list with 2 rows and 3 columns of strings (e.g., names of fruits). Print the 2-D list to confirm the structure.

3. access_update.py

   Create a list of scores [12, 18, 9, 21, 15]. Then:

   • Print the third item.
   • Change the last item to 20.
   • Print the length of the list.

AO2 – Applying Knowledge

1. list_methods.py

   Start with data = [4, 5].

   • Append one new number.

   • Extend the list with two more numbers.

   • Insert a number at index 1.

     Print the final list after each operation.

2. trace_output.py

   Copy this list into your program: names = ["Ava", "Ben", "Chen", "Dia"].

   Add print statements to show what happens when:

   • You print the second item.
   • You replace "Chen" with "Chan".
   • You print the length of the list.
   • You print the first two items using slicing.

3. fix_error.py

   The following code contains an error. Run it, explain the error in comments, then correct it:

   items = [2, 3, 5]
   items[3] = 7
   

AO3 – Problem-Solving & Analysis

1. two_d_indexing.py

   Use the following 2D list:

   grid = [
       [2, 4, 6],
       [1, 3, 5]
   ]
   

   • Print the value 3.
   • Change the value 6 to 0.
   • Print the number of rows and columns in the grid.

2. why_lists.py

   Write a short program that stores five test scores in a list.

   In a comment at the end, explain why using a list is better than using five separate variables.

3. slicing.py

   Start with nums = [10, 20, 30, 40, 50].

   Write a program that slices the list to return [20, 30, 40]. Print the result.
