本文实例讲述了Python简单实现子网掩码转换的方法。分享给大家供大家参考,具体如下:

这里实现将子网掩码长度转换为具体的子网掩码地址:

def exchange_maskint(mask_int):
  bin_arr = ['0' for i in range(32)]
  for i in range(mask_int):
    bin_arr[i] = '1'
  tmpmask = [''.join(bin_arr[i * 8:i * 8 + 8]) for i in range(4)]
  tmpmask = [str(int(tmpstr, 2)) for tmpstr in tmpmask]
  return '.'.join(tmpmask)
if __name__ == '__main__':
  print exchange_maskint(24)
