OCTET STR：如何转换为 HEX

Question

您能否就如何解码八位字节字符串并获取 mac-地址提出建议？

使用 easysnmp 时：net-snmp python bindings [http://easysnmp.readthedocs.org/en/latest/]

例如； none下面表示的value对应一个mac地址。

for x in ipNetToMediaPhysAddress:
    print x.oid, x.oid_index,  repr(x.value), ':'.join([i.encode("hex") for i in repr(x.value)])

ipNetToMediaPhysAddress 768.194.146.118.1 u'\x08\x81\xf4\x9bo\xc0' 75:27:5c:78:30:38:5c:78:38:31:5c:78:66:34:5c:78:39:62:6f:5c:78:63:30:27
ipNetToMediaPhysAddress 768.194.146.118.3 u'\x00\t\xb7f@@' 75:27:5c:78:30:30:5c:74:5c:78:62:37:66:40:40:27
ipNetToMediaPhysAddress 768.194.146.118.8 u'\x00\x1f\x12\xb3\xdc\xac' 75:27:5c:78:30:30:5c:78:31:66:5c:78:31:32:5c:78:62:33:5c:78:64:63:5c:78:61:63:27
ipNetToMediaPhysAddress 768.194.146.118.10 u'l\x9c\xed(\xd1\xf3' 75:27:6c:5c:78:39:63:5c:78:65:64:28:5c:78:64:31:5c:78:66:33:27

ipNetToMediaPhysAddress 768.194.146.118.28 u"\E']\xcdK" 75:22:5c:5c:45:27:5d:5c:78:63:64:4b:22

能否请您帮助将 value 转换为 mac 地址的有效十六进制表示形式？
