Question

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

Answer 1

The code you've provided primarily demonstrates **Iteration**. Let's break it down:

1. **Iteration**: The part of the code that iterates over the `colourList` using a `FOR` loop is the primary example of iteration. This allows the program to repeat a block of code (in this case, printing each colour) for each item in the list.

2. **Sequencing**: This refers to the order in which the statements are executed. The program first prints the message "The rainbow colours are: " and then starts to iterate through the list. This linear execution of statements is an example of sequencing.

3. **Selection**: This construct is not explicitly used in your code. Selection usually refers to decision-making structures like `if` statements that allow a program to execute certain blocks of code based on conditions. Since your example doesn't include any conditional statements, selection is not represented here.

So, in summary:
- The provided code demonstrates **Iteration** (through the `FOR` loop), and it includes **Sequencing** (the order of execution of statements), but does not include **Selection**.
