def rotate_encode(s):
    """Create a function rotate_encode that takes a string as an argument and
    returns a string encoded with the alphabet being rotated. 
    The alphabet should be rotated in a manner such that the letters 
    shift down by [two multiplied by two] places.
    For example:
    rotate_encode('hi') returns 'lm'
    rotate_encode('asdfghjkl') returns 'ewhjklnop'
    rotate_encode('gf') returns 'kj'
    rotate_encode('et') returns 'ix'
    
    Example solution:
    # line 1
    d = 'abcdefghijklnmopqrstuvwxyz'
    # line 2
    out = ''
    # line 3
    for c in s:
        # line 4
        if c in d:
            # line 5
            out += d[(d.index(c)+2*2) % 26]
        # line 6
        else:
            # line 7
            out += c
    # line 8
