[Tutor] Need help with sockets

[James Duffy]

For a part of a program, I need to send a text string to another machine in
a IM style app. I've done this in C# but never in python. The server is in
C# so I just need a client side program that can listen for and display
incoming messages as well as send messages. Ive managed to make a socket and
connect but I don't know how to setup a listen thread and a sender function.
Can someone help? Below is C# code for the listener/send function of my
client that id made. I basically hafta turn this into python. This method
runs inside a thread.

 

 

 

 

void RunClient() 

{

TcpClient myClient; // instantiate TcpClient for sending data to server 

try 

{

Output to screen: Attempting connection\r\n" 

// Step 1: Create TcpClient 

myClient = new TcpClient(); 

// Step 2: Connect to server 

myClient.Connect(address.Text,int.Parse(port.Text)); 

// Step 3: Create a Network Stream associated with TcpClient 

myNetStream = myClient.GetStream();

// Step 4: Create objects for writing and reading across stream 

myWriter = new BinaryWriter(myNetStream); 

myReader = new BinaryReader(myNetStream); 

// loop until server signals termination 

do 

{

// Step 5: Processing phase 

try 

{

// read message from server 

message = myReader.ReadString();

inbound.Text +="\r\n" + message; 

}

// handle exception if error in reading server data 

catch (Exception) 

{

System.Environment.Exit( System.Environment.ExitCode); 

}

} 

while (message != "SERVER>>> TERMINATE"); 

status.Text += "\r\nClosing connection.\r\n"; 

// Step 6: Close connection 

myWriter.Close();

myReader.Close();

myNetStream.Close();

myClient.Close();

Application.Exit(); 

}

// handle exception if error in establishing connection 

Catch (Exception error) 

{

MessageBox.Show(error.ToString()); 

}

}
