Question
What does the following list comprehension produce?
result = [x**2 for x in range(5) if x % 2 == 0] print(result)Solution
The list comprehension iterates through numbers 0 to 4 (range(5)) and filters those divisible by 2 (if x % 2 == 0). For these numbers, their squares are computed and added to the result. • Step-by-step values: o 0 % 2 == 0 → 0**2 = 0 o 2 % 2 == 0 → 2**2 = 4 o 4 % 2 == 0 → 4**2 = 16 Thus, the final output is [0, 4, 16]. ________________________________________ Why Other Options Are Incorrect: 1. `[0, 1, 4, 9, 16]: Includes all numbers, ignoring the filter condition. 2. `[1, 9]: Includes squares of odd numbers only. 3. **[4, 16]:** Excludes 0`, which is even. 4. Error: The code is valid and produces the expected output.
