深圳大学学子请教D版配置问题，TypeError: can't concat str to bytes

[CaesarYP]

wireshark抓包后在线配置器conf文件如下：
server = '172.30.255.2'
username = '412264'
password = '666CaesarYP'
CONTROLCHECKSTATUS = '\x20'
ADAPTERNUM = '\x04'
host_ip = '172.24.173.94'
IPDOG = '\x01'
host_name = 'fuyumi'
PRIMARY_DNS = '192.168.1.1'
dhcp_server = '172.30.254.81'
AUTH_VERSION = '\x30\x00'
mac = 0x12c7d66c1102
host_os = 'Windows 10'
KEEP_ALIVE_VERSION = '\xdc\x02'
ror_version = False（已经试过改为True，无效）

用latest-wired-python3.py测试结果如下：
auth svr: 172.30.255.2
username: 412264
password: 666CaesarYP
mac: 0x12c7d66c110
bind ip: 0.0.0.0

请求解答配置哪里有问题，谢谢！

python3 bytes 和 string有区别，从网络收到的是bytes ，CONTROLCHECKSTATUS = '\x20'是str，写成 CONTROLCHECKSTATUS = b'\x20'就是 一个字节长度的bytes，就可以加了。这个主要是python问题，很多linux自带的是python2，你这个是python3，导致字符串和bytes兼容问题
