,PART I: VARIABLES, DATA TYPES & EXPRESSIONS (Questions
1-25)


1. What is the output of the following code?
python
x=5
y=2
print(x / y)
• A) 2
• B) 2.5
• C) 3
• D) 2.0
• E) Error
Answer: B
Rationale: In Python 3, the / operator performs floating-
point division, returning a float. = 2.5.


2. What is the output of the following code?
python

, x=5
y=2
print(x // y)
• A) 2
• B) 2.5
• C) 3
• D) 2.0
• E) Error
Answer: A
Rationale: The // operator performs integer (floor) division,
returning the quotient without the remainder. 5 // 2 = 2.


3. What is the output of the following code?
python
x=5
y=2
print(x % y)
• A) 0
• B) 1
