colourList = ["red", "orange", "yellow", "green", "blue", "indigo", "violet"] PRINT ("The rainbow colours are: ") FOR colour in colourList: PRINT colour This code uses: Selection Iteration Sequencing

The provided code snippet illustrates a simple structure in programming. Let's analyze the components you mentioned: selection, iteration, and sequencing.

1. Sequencing: This is the order in which statements are executed. In your code:

   PRINT ("The rainbow colours are: ")
   

   is executed first, followed by the iteration block that prints each color. This shows a clear sequence of operations.

2. Iteration: This is the process of repeating a block of code. In the provided code:

   FOR colour in colourList:
       PRINT colour
   

   This part represents iteration because it repeats the print action for each color in the colourList.

3. Selection: This typically involves making choices based on conditions (like if, else, etc.). However, in the provided code snippet, there is no selection structure present. You are simply printing each color without any condition or choice being made.

To summarize, your code demonstrates sequencing and iteration, but selection is not utilized in this specific snippet.

If you want to introduce selection, you could add a conditional statement to print only certain colors, like this:

colourList = ["red", "orange", "yellow", "green", "blue", "indigo", "violet"]
print("The rainbow colours are:")
for colour in colourList:
    if colour in ["red", "blue", "violet"]:  # This is the selection part
        print(colour)

This modified version uses selection to filter which colors to print.
