PCEP Practice Question: Data Types, Variables, Basic I/O and Operators
Exhibit
Refer to the exhibit. >>> x = 10 >>> y = 3 >>> z = x // y >>> print(z)
What is the output of the code in the exhibit?
⚠ Common exam trap
Python Institute often tests the distinction between / (true division returning a float) and // (floor division returning an int), tricking candidates who confuse the two operators or forget that integer division discards the remainder.
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
✓
3
The code performs integer division using the // operator, which in Python returns the floor of the division result for positive numbers. Since 10 // 3 equals 3 (the integer part of 10/3), the output is 3. Option A is correct because integer division discards the fractional part.
