Problem p03252 (python)

Fixed submission:
s = input()
t = input()
start = [-1]*30
goal = [-1]*30
count = 0
for i in range(0,len(s)):
    a = ord(s[i])-ord("a")
    b = ord(t[i])-ord("a")
    if start[a] != -1 or goal[b] != -1:
        if start[a] != b or goal[b] != a:
            count = 1
            break
    else:
        start[a] = b

if count == 1:
