What is the output of the following Python expression: `[x**2 for x in range(5) if x % 2 == 1]`?
Answer and explanation
Correct answer: B. `[1, 9]`
- Step 1: The `range(5)` function generates integers .
- Step 2: The condition `if x % 2 == 1` filters for odd numbers: and . Squaring them yields and , producing `[1, 9]`.
Answer
`[1, 9]`.
Why not the others: '`[0, 4, 16]`' filters for even numbers; '`[1, 4, 9]`' includes even number 2; '`[0, 1, 4, 9, 16]`' squares all numbers without filtering.
