PCEP Computer Programming and Python Fundamentals Practice Question
Which THREE of the following are valid ways to create a list with elements 1, 2, 3? (Choose Three)
⚠ Common exam trap
The PCEP exam often tests the distinction between list, tuple, and set literals, so candidates mistakenly choose curly-brace or parenthesis syntax as valid list creation methods.

Correct answer & explanation
✓
[1,2,3]
It uses the literal list syntax with square brackets and commas to directly create a list containing the integers 1, 2, and 3. This is the most straightforward and explicit way to define a list in Python.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
[1,2,3]
Why this is correct
Standard list literal.
- ✓
list(range(1,4))
Why this is correct
range(1,4) generates 1,2,3 and list() converts to list.
- ✗
(1,2,3)
Why it's wrong here
Parentheses create a tuple, not a list.
- ✓
[x for x in range(1,4)]
Why this is correct
List comprehension yields [1,2,3].
- ✗
{1,2,3}
Why it's wrong here
Curly braces with values create a set.
