PCEP Practice Question: Data Types, Variables, Basic I/O and Operators
Given the code: x = 10; y = 3.0; z = x / y; print(type(z)). What is the output?
⚠ Common exam trap
Python Institute often tests the distinction between / (true division) and // (floor division), trapping candidates who mistakenly think dividing an integer by a float returns an integer or that the result type depends on exact divisibility.

Correct answer & explanation
✓
<class 'float'>
In Python, when you divide an integer by a float using the / operator, the result is always a float. Here, x is an integer (10) and y is a float (3.0), so z = 10 / 3.0 evaluates to 3.3333333333333335, which is of type float. The print(type(z)) outputs <class 'float'>, making option B correct.
