PCEP Computer Programming and Python Fundamentals Practice Question
Which TWO of the following statements about Python's for loop are correct? (Choose Two)
⚠ Common exam trap
The PCEP exam often tests the misconception that a `for` loop always executes at least once, but in reality it can iterate zero times over an empty sequence, and they also test the less-known fact that `for` loops support an `else` clause.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
It can iterate over any sequence
A `for` loop in Python is designed to iterate over any iterable sequence, such as lists, tuples, strings, dictionaries, or ranges. This is a fundamental property of the `for` loop, which retrieves each item from the sequence in order until the sequence is exhausted.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
It can be used with a while loop condition
Why it's wrong here
Incorrect; for and while are separate constructs.
- ✓
It can iterate over any sequence
Why this is correct
For works with lists, tuples, strings, etc.
- ✗
It always executes at least once
Why it's wrong here
If the sequence is empty, the loop body does not execute.
- ✓
It can be used with an else clause
Why this is correct
Yes, the else block runs after normal loop completion.
- ✗
It is the only loop in Python
Why it's wrong here
Python also has while loops.
