Problem p02761 (python)

Fixed submission:
n,m = map(int,input().split())
sc = [[i for i in map(int,input().split())] for j in range(m)]
start = 0
goal = 0
if n==1:
  start = 0
  goal = 9
elif n==2:
  start = 10
  goal = 99
elif n==3:
  start = 100
  goal = 999

flag = 1
ans = -1
for num in range(start,goal+1):
  flag = 1
  for i in range(m):
    if str(num)[sc[i][0]-1] != str(sc[i][1]): #両辺ともちゃんとstrで変換
      flag = 0
  if flag == 1:
    ans = num
    break

print(ans)
