Python client can not communicate with ruby server. I get [Errno 10061] No connection could be made because the target machine actively refused it

I have the intention of running machine learning algorithms written in Python on data in a database of a Ruby on Rails app. After some research I have discovered sockets and therefore created a Ruby server and Python client. I am running them both on two different command prompt terminals.

Here is the Ruby server code:

require "socket"

server = TCPServer.open(2000)

loop {
  client = server.accept
  client.puts(Time.now.ctime)
  client.puts "Closing the connection. Bye!"
  client.close
  }

Here is the Python client code:

import socket

s = socket.socket()
host = "localhost"
port = 2000
s.connect((host , port))

I do not understand where the problem is. Kindly assist.

Given insightful answers to my question above the code Ruby server and Python client should be as below.

For the Ruby server:

require "socket" # Get sockets from stdlib

server = TCPServer.open("127.0.0.1" , 2000) # Socket to listen on port 2000

loop {                     # Server runs forever
  client = server.accept   # Wait for a client to connect
  client.puts(Time.now.ctime) # Send the time to the client
  client.puts "Closing the connection. Bye!" 
  client.close # Disconnect from the client

  }

For the Python client:

import socket # Import socket module

s = socket.socket() # Create a socket object
host = "127.0.0.1"
port = 2000 # Reserve a port for your service.
s.connect((host , port))
print s.recv(1024)
s.close() # Close the socket when done

The open() method of the TCPServer class in Ruby takes two parameters. The first being the host name and the second the port i.e

TCPServer.open(hostname , port)
