Python3如何实现个位数字和十位数字对调,其乘积不变

count = 0

for i in range(11, 100):
  first_left = i // 10
  first_right = i % 10

  if first_left == first_right:  #减少程序循环次数，因为后面的 for j in range(i + 1, 100)
    continue    # 已经解决了11、22 重复出现的不在此列 和 13*62与62*13不在队列

  for j in range(i + 1, 100):   #遍历出数字并找出个位和十位
    second_left = j // 10
    second_right = j % 10

    if second_left == second_right:  #同理减少循环次数
      continue

    newfirst = first_right * 10 + first_left
    newsecOnd= second_right * 10 + second_left

    if i * j == newfirst * newsecond: #进行if判断
      print(&＃39;{} * {} = {} * {}&＃39;.format(i, j, newfirst, newsecond))

      count += 1

print(count)
