Why am I getting 'TypeError: a bytes-like object is required, not 'str'' when running my WHOIS script in the Linux terminal?

I am creating a basic "whois" script, but it is not working. When I try to run it in the Linux terminal, it returns the error:

"TypeError: a bytes-like object is required, not 'str'" indicated inthe line of code: s.send(sys.argv[1]+"\r"+"\n").
