Intro to Computing - How Data is Represented

In a compression algorithm, a developer uses the following code snippet:

if data == None:
  compress(data)

What is the likely problem here?

AThe condition should check if data is not None before compressing

BThe compress function is called without parentheses

CThe code compresses data only when it is None

DThe code uses == instead of = for assignment

Step-by-Step Solution

Solution:

Step 1: Understand the condition logic
The code compresses data only if data equals None (no data).
Step 2: Identify logical error
Compressing None is meaningless; should compress when data exists.
Final Answer:
The code compresses data only when it is None -> Option C
Quick Check:
Compressing None = Logical error [OK]

Quick Trick: Check data exists before compressing [OK]
