Sockets can't send data

Question

Code

host = "127.0.0.1"
port=4446
from socket import *
s = socket(AF_INET, SOCK_STREAM)
s.bind((host,port))

s.listen(1)

print("Listening for connections...")

q,addr = s.accept()

data = input("Type something in")
q.send(data)
s.close

Error

TypeError:'str' does not support the buffer interface

So I know that there are hundreds of questions on here about this error but I still cant think up a solution, can one of you guys help me out? :(

In Python 3, strings are Unicode values, but sockets can only take encoded bytes.

Encode your data first:

q.send(data.encode('utf8'))

I picked UTF-8 here as the codec to use, but you need to consciously pick a encoding suitable to your specific application.

Should I make a new question about a client problem I just got, or post it here? – user3241744 Feb 15 '14 at 15:52
I'd make that a new question. – Martijn Pieters Feb 15 '14 at 15:52
I have to wait 20 minutes between questions :( IMM NOT A ROBOAT – user3241744 Feb 15 '14 at 15:56
@user3241744: pick your questions carefully, make sure we have a clear example of what is going wrong, and the 20 minutes will fly by. The rate limit is not there just for robots, btw. – Martijn Pieters Feb 15 '14 at 15:57
Haha, 20 minutes already went by that was fast. – user3241744 Feb 15 '14 at 16:11

Strings are Unicode objects in python 3. You need to encode it to a byte string before sending.

Data.encode("ASCII")
