I don't see why you think that's an ugly hack.

def printitems(sequence, count=5):
    """Print count items of sequence per line."""
    numrows = len(sequence)//count
    if len(sequence)%count != 0: numrows += 1
    for start in range(0, numrows):
        items = sequence[start*count:(start+1)*count]
        for item in items:
            print item,
        print
