请编写一个函数实现将IP地址转换成一个整数。(3分) 如 10.3.9.12 转换规则为: 10 00001010 3 00000011 9 00001001 12 00001100 再将以上二进制拼接起来计算十进制结果:00001010 00000011 00001001 00001100 = ? #用Python获取本机ip地址 from socket import gethostbyname_ex, gethostname local_IP_list = gethostbyname_ex(gethostname()) local_IP = gethostbyname_ex(gethostname())[2][2] print(local_IP_list) print(local_IP) 本题答案: def ipfunc(ip): a = ip.split('.') s = '' l = [] for i in a: i = bin(int(i))[2:] i = i.rjust(8, '0') l.append(i) s = s.join(l) return s ipfunc(local_IP)
