Question

choose the correct syntax to slice each of the following elements from the list: arr = ['a', 'b', 'c', 'd', 'e', 'f', 'g']
arr(2:6)
arr(4:6)
arr(3:7)
arr(:3)
arr(4:)
arr(0:2)
arr(2:5)
arr(:2)

Answer 1

Use square brackets for slicing. For arr = ['a','b','c','d','e','f','g']:

- arr(2:6) -> arr[2:6] => ['c', 'd', 'e', 'f']
- arr(4:6) -> arr[4:6] => ['e', 'f']
- arr(3:7) -> arr[3:7] => ['d', 'e', 'f', 'g']
- arr(:3) -> arr[:3] => ['a', 'b', 'c']
- arr(4:) -> arr[4:] => ['e', 'f', 'g']
- arr(0:2) -> arr[0:2] => ['a', 'b']
- arr(2:5) -> arr[2:5] => ['c', 'd', 'e']
- arr(:2) -> arr[:2] => ['a', 'b']
