Question 312 of 498
PCEP Practice Question: Data Types, Variables, Basic I/O and Operators
A program prompts a user for their age using input(). Which line of code correctly stores the age as an integer?
⚠ Common exam trap
The trap here is that candidates often forget `input()` returns a string and assume the user's typed digits are automatically stored as a number, leading them to pick option D without any conversion.
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
✓
age = int(input("Enter age: "))
The `int()` function explicitly converts the string returned by `input()` into an integer, which is required for storing a numeric age value. The `input()` function always returns a string in Python, so without conversion, arithmetic operations would fail or produce unexpected results.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
age = str(input("Enter age: "))
Why it's wrong here
This converts to string (input already returns string).
- ✗
age = float(input("Enter age: "))
Why it's wrong here
This converts to float, not int.
- ✓
age = int(input("Enter age: "))
Why this is correct
Correctly converts input string to integer.
- ✗
age = input("Enter age: ")
Why it's wrong here
This stores a string, not an integer.
