sockets - 'str' does not support the buffer interface - Python 3 -

this question has answer here:

• typeerror: str not support buffer interface [duplicate] 1 answer

import socket  servername = "hostname" serverport = 12000  clientsocket = socket.socket(socket.af_inet, socket.sock_dgram) message = input('input lowercase sentence:') clientsocket.sendto(message, (servername, serverport)) modifiedmessage, serveraddress = clientsocket.recvfrom(2048) print (modifiedmessage) clientsocket.close() 

gives error

traceback (most recent call last):   file "c:/python34/server1.py", line 11, in <module>     clientsocket.sendto(message, (servername, serverport)) typeerror: 'str' not support buffer interface 

what do?

i've encode code

import socket  servername = "hostname" serverport = 12000  clientsocket = socket.socket(socket.af_inet,socket.sock_dgram)   message = input('input lowercase sentence:').encode('ascii')  clientsocket.sendto(message,(servername, serverport))  modifiedmessage, serveraddress = clientsocket.recvfrom(2048)   print (modifiedmessage.decode('ascii'))  clientsocket.close() 

but still error

traceback (most recent call last):   file "j:\sistem jaringan\task i\client.py", line 11, in <module>     clientsocket.sendto(message,(servername, serverport)) socket.gaierror: [errno 11004] getaddrinfo failed 

how can fix it?

sockets sent bytes other end of connection. encode strings bytes before trying send. in sendto method, change message message.encode(). add argument encoding='xyz' if not want default utf-8 encoding. modifiedmessage receive bytes, , may want decode string.
