有些需要支持ipv6的功能，在展示ip時當然是展示簡寫ip，但是在收包的時候都是全寫ip，需要將其轉換：

# -*- coding=UTF-8 -*- def ipv6_trans(addr_v6):list_v = []for x in addr_v6.split(":"):if x == "0000" or x == "0":list_v.append("0")else:list_v.append(x.lstrip("0"))first, second = 0, 0for i in range(len(list_v)-1):if first == second and (list_v[i+1] != "0" or list_v[i] != "0"):continueelif first == second and list_v[i] == "0" and list_v[i+1] == "0":first, second = i, i+1elif list_v[i] == "0":second += 1else:breakif second == (len(list_v)-1) and list_v[-1] == "0":second += 1if first != second:a, b, c = list_v[0: first], list_v[first: second], list_v[second:]ret = ":".join(a) + "::" + ":".join(c)else:ret = ":".join(list_v)return retdef main():# ipv6 = "ff06:0:0:0:0:0:0:c3"ipv6_1 = "0000:ff06:0000:0000:0000:0000:0000:0000"ipv6_2 = "0000:0000:0000:0000:0000:0000:0000:0000"ipv6_3 = "ff02:0000:0000:0000:0000:0001:ff00:0001"ipv6_4 = "fd82:139b:8752:0000:246e:0031:888c:36db"ipv6_5 = "fd82:0000:8752:0000:0000:0031:888c:36db"ipv6_6 = "fd82:0000:0000:8752:0000:0031:888c:36db"ipv6_list = [ipv6_1, ipv6_2, ipv6_3, ipv6_4, ipv6_5, ipv6_6]for element in ipv6_list:print(ipv6_trans(element))if __name__ == '__main__':main()

輸出結果：

0:ff06:: :: ff02::1:ff00:1 fd82:139b:8752:0:246e:31:888c:36db fd82:0:8752::31:888c:36db fd82::8752:0:31:888c:36db
