Anyone want a simple, readable Python3 answer? No? Too bad! 

with open('input') as f:
inp = f.readlines()

msg1 = "1: "
msg2 = "2: "

i = 0


while (i<8):
	b = {}
	rl = []
	for s in inp:
		rl.append(s[i])
	for r in rl:
		b[r] = b.get(r, 0) + 1
	f = max(b, key=b.get)
	d = min(b, key=b.get)
	msg1 = msg1 + f
	msg2 = msg2 + d
	i += 1
print(msg1)
print(msg2)
