What output will a code generation agent produce for this instruction: Generate a Python function that returns True if a number is even, else False?

Adef is_even(n): return n % 2 = 0
Bdef is_even(n): return n / 2 == 0
Cdef is_even(n): return n % 2 == 0
Ddef is_even(n): if n % 2 == 1: return True
Step-by-Step Solution
Solution:
  1. Step 1: Understand the correct way to check even numbers in Python

    Using modulo operator '%' with 2 and comparing to 0 checks evenness.
  2. Step 2: Evaluate each option for correctness

    def is_even(n): return n % 2 == 0 correctly uses 'n % 2 == 0'. def is_even(n): return n / 2 == 0 uses division incorrectly, C uses assignment instead of comparison, D returns True for odd numbers.
  3. Final Answer:

    def is_even(n): return n % 2 == 0 -> Option C
  4. Quick Check:

    Even check = n % 2 == 0 [OK]
Quick Trick: Use modulo operator to check even numbers [OK]
Common Mistakes:
  • Using division instead of modulo
  • Using assignment '=' instead of '=='
  • Returning True for odd numbers
