PCEP Practice Question: Data Types, Variables, Basic I/O and Operators
Exhibit
Refer to the exhibit. x = 7 y = 2 result = x / y print(type(result))
What is the output of the code?
⚠ Common exam trap
Python Institute often tests the distinction between `/` (true division) and `//` (floor division) in Python 3, and the trap here is that candidates mistakenly think integer division with `/` yields an integer, confusing it with Python 2 behavior or the `//` operator.
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
✓
<class 'float'>
The code uses the `type()` function to determine the data type of the result of the expression `10 / 3`. In Python 3, the `/` operator always performs true division, which returns a floating-point number even if the operands are integers. Therefore, `10 / 3` evaluates to `3.3333333333333335` (a float), and `type()` returns `<class 'float'>`. Option C is correct.
