PCEP Practice Question: Data Types, Variables, Basic I/O and Operators
A developer writes a script to calculate the average of three numbers: avg = (a + b + c) / 3. If a=5, b=10, c=15, what is the data type of avg?
⚠ Common exam trap
Python Institute often tests the distinction between / (true division, returns float) and // (floor division, returns int) to trap candidates who assume integer division returns an integer.
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
✓
float
In Python, the division operator (/) always returns a float, even when dividing integers that result in a whole number. Here, (5 + 10 + 15) / 3 equals 30 / 3, which yields 10.0, a float. Therefore, the data type of avg is float.
