Printing via UDP in Python

TO BE TESTED

import socket
import system
udpSocket=socket.socket(socket.AF_INET,socket.SOCK_DGRAM)
message ="SEND THIS TO ZEBRA"
ip='192.168.0.100'
port=20000
udpSocket.sendto(message,(ip,port))

Socket clientSocket = new Socket(AddressFamily.InterNetwork,

SocketType.Stream, ProtocolType.Tcp);
clientSocket.NoDelay = true;

IPAddress ip = IPAddress.Parse("192.168.192.6");
IPEndPoint ipep = new IPEndPoint(ip, 9100);
clientSocket.Connect(ipep);

byte[] fileBytes = File.ReadAllBytes("test.txt");

clientSocket.Send(fileBytes);
clientSocket.Close(); 

local http servers

The following starts a basic http server locally in the current directory;

python 2.x

Python misc

def myFunction(prices, credit):

        for b in range(a+1,(len(prices))):
            if(prices[a]+prices[b]==credit):
                if (prices[a]>prices[b]):
                    myT=[prices[b],prices[a]]
                    return(myT)
                else:
                    myT=(prices[a],prices[b])
                    return(myT)
