Convert an int and bytearray into a ByteString Python struct Socket -

-

i need send 1 int und 1 bytearray(200) through socket server. socket.send() function accpets 1 string need int , bytearray bytes in 1 string. tryed convert both string struct.pack(), working int not bytearray.

    s = socket.socket(socket.af_inet, socket.sock_stream)     s.connect((tcp_ip, tcp_port))     print "connected to: ",  s.getpeername()     #trying put int , bytearray 1 string     a= 02 # int     b= bytearray(200) #bytearray     c = struct.pack("b", a)     c += b        s.send(c)     print s.recv(1024)

concatenate them:

>>> import struct >>> struct.pack('<l', 1234) + bytearray([0]*10) b'\xd2\x04\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00'

or specify bytearray:

>>> struct.pack('<l10s', 1234, bytearray([0]*10)) # in python 3.x # struct.pack('<l10s', 1234, bytes(bytearray([0]*10))) # in python 2.x b'\xd2\x04\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00'
