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)
