Thanks a lot, as a beginner, this program gave me enough confidence to go further.

Wish the series continued in python3.4!  You did a great job.

Going to have to search how to send different formats with Python3.4.

Thanks! Can't wait for the next installment.

Can you please create the other videos for this tutorial! I really love the way you explained this. It made sooo much sense to me the way you presented it!!!

[wabeti]

Very informative tutorial! Keep up the great work!

why stopped? I await for more videos (TCP, etc)

import socket # Import socket module
import time

host = "localhost" # Get local machine name
port = 5454# Reserve a port for your service.
data = "just some text"
data = data.encode('utf-8')

s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) # Create a socket object

while 1:
s.sendto(data, (host, port))
print ("sent " + data.decode('utf-8'))
time.sleep(1)



#this works fine in python 3 versions

this was a great video.. but i was really hoping that you would have the rest of the videos on your channel =(

Very good tutorial. I think it is in Python 2.x. Are there any changes in Python 3. If so can you do one for Python 3 as well. Thanks.

@nnikitaka I cant see why not but im not familiar with the python blender interface

[nnikitaka]

Can u use this for a game that is made a blender?, blender uses python as a programing language

[SamJoseph]

great - when's the next in the series coming out?

[AKSoapy]

Great tutorial! I have a question about Python. In C, you can make functions. How would you do that in Python?

[JoshMcCullochNZ]

@aten747 Is this on the sender or receiver script?

[tango]

if I wanted to receive different data each time would I need to make a new script or put in another while loop in their?

[JoshMcCullochNZ]

Strings in python 3 are unicode by default. But I imagine that sockets need a buffer of bytes. To make ascii strings put a "b" in front of your string like so b"hello world". I haven't got python3 installed to test this so get back to me if it doesn't work.

@Hcwool
Of course. Your can send anything you can transform into a string. Yous just need to convert it back at the other end. Ill show that in a future video

[excaliberx]

I got an error with  s.sendto (data, (HOST, PORT))

[atenofficial]

@largestpixel i tried sending it over land and i get the "out of context address" windows error, how do i fix this?
