使用加密功能将Python 2转换为3

Question

脚本是为Python2编写的，但我需要将它转换为Python3。

结果：

Traceback (most recent call last):
   File "tplink_smartplug.py", line 105, in <module>
       sock_tcp.send(encrypt(cmd))
   File "tplink_smartplug.py", line 70, in encrypt
       result += chr(a)

TypeError:不能将str连接到字节

# XOR Autokey Cipher with starting key = 171
def encrypt(string):
    key = 171
    result = pack('>I', len(string))
    for i in string:
        a = key ^ ord(i)
        key = a
        result += chr(a)   #line70
    return result

def decrypt(string):
    key = 171
    result = ""
    for i in string:
        a = key ^ ord(i)
        key = ord(i)
        result += chr(a)
    return result

# Send command and receive reply
try:
    sock_tcp = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    sock_tcp.connect((ip, port))
    sock_tcp.send(encrypt(cmd))    #line105
    data = sock_tcp.recv(2048)
    sock_tcp.close()

    print(("Sent:     ", cmd ))
    print(("Received: ", decrypt(data[4:]) ))
except socket.error:
    quit("Cound not connect to host " + ip + ":" + str(port))
