I run on Python3 and i get the error on client
python3 client.py Traceback (most recent call last): File "client.py", line 13, in <module> s.connect((sys.argv[0], int(sys.argv[1]))) IndexError: list index out of range
Does anyone know how to solve this?

I think you have not given any arguments when running the code

I think the arguments should be IP address and port number

Ex : python client.py 127.0.0.1 4444
Or try giving arguments other way around

Now i got the following error:

python3 client.py 127.0.0.1 4444 Traceback (most recent call last): File "client.py", line 13, in <module> s.connect((sys.argv[0], int(sys.argv[1]))) ValueError: invalid literal for int() with base 10: '127.0.0.1'

if you have made any changes to the code on line 13 , try comparing your code and this gist
I can say for sure the code in gist works .

Oh yeah you are right, it is my fault. I accidentally had changed an int value from 0 to 1. Thank you very much for your time!

Can some one say how to stop listening from serverside with a keyboard interrupt like
if keyboard.is_pressed("q"):
stream.close()
serversocket.close()
audio.terminate()

I know these steps but I don't know where to insert in your code,so kindly can you give me a solution
