Python Coding Challenge - Question with Answer (ID 181026)

 

Explanation:

Step 1: Understand the round() function

Python's round() function rounds a number to the nearest integer when no second argument is provided.

round(2.5)round(3.5)

Normally, you might expect both numbers to round upward. However, Python uses a special rule when a number falls exactly halfway between two integers.

Step 2: Evaluate round(2.5)

The number 2.5 lies exactly between 2 and 3.

Python uses the round-half-to-even rule: when the number is exactly halfway, it rounds to the nearest even integer.

- 2 is even.

- 3 is odd.

Therefore:

round(2.5)  # 2

Step 3: Evaluate round(3.5)

The number 3.5 lies exactly between 3 and 4.

- 3 is odd.

- 4 is even.

Therefore, Python rounds to 4:

round(3.5)  # 4

Step 4: Understand how print() works

print(round(2.5), round(3.5))

Python evaluates both function calls and prints their results separated by a space.

- First value: 2

- Second value: 4

✅ Final Output

2 4
