In Python, what word do we use for doing something repeatedly?

• Iteration

• Selection

• Sequence

• Repetition

A switch statement is an example of....

• Iteration

• Sequence

• Selection

count = 1

How do I add 1 to the variable count?

• count + 1

• count = count + 1

• count++

• count = count * 1

This is an example of ...

• Sequence

• Selection

• Iteration

In Python, 'sequence' means...

• The execution of statements one after the other in order.

• A collection of items in no particular order.

In this code snippet, myValue is ...

• Something else

• A boolean

• integer
• string
• Boolean
• float
• list
• set
• tuple

Decomposition is....

• Combining multiple solutions into a single, complex solution to address a problem in a comprehensive manner.

• Breaking a problem down into smaller sub-problems, so those can be tackled individually.

• Repeatedly testing a solution until it no longer fails, ensuring all possibilities are explored and the most efficient answer is found.

Algorithmic thinking is...

• Deciding on the order that instructions are carried out and identifying decisions that need to be made by the computer.

• Memorising code snippets to implement them directly without understanding what they really do.

• Focusing solely on how a program looks or feels, neglecting the underlying logic and structure.

What is the process of changing one data type to another called?

• Data conversion
• Type casting
• Data shifting
• Type swapping
