Correct answer & explanation

✓

list = list(range(1, 4))

`list(range(1, 4))` creates a list from the range object that generates numbers 1, 2, and 3 (the `range` function stops before the stop value 4). This is a common Python idiom for converting a range into a list.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

✓
list = list(range(1, 4))
Why this is correct
Valid: range creates sequence, list() converts to list.
✓
list = [1, 2, 3]
Why this is correct
Valid list literal.
✗
list = [1, 2, 3]]
Why it's wrong here
Extra closing bracket causes SyntaxError.
✗
list = (1, 2, 3)
Why it's wrong here
Creates a tuple, not a list.
✗
list = [1; 2; 3]
Why it's wrong here
Invalid syntax; semicolons not allowed in list literals.
