In this blog, we will learn how to create a basic chat application in Python. This blog guides you through methods to implement a chat application, from using sockets for simple messaging to creating a GUI with Tkinter.


In today's digital world, communication is easier than ever, and creating a simple chat application can be a fun and educational project. Whether you are a beginner or an experienced programmer, this blog will guide you through the process of building a basic chat application in Python. We will explore different methods to implement chat functionality and provide code examples for each step, ensuring you have a working chat application by the end.

Method 1: Using Sockets for Simple Messaging

To start, we will implement a basic chat application using sockets, which provide a low-level network communication interface. Python's socket library allows us to create a server and client for our chat application. Here's the code for our chat server:

import socket

# Create a socket
server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
host = ""
port = 12345

# Bind the socket to the address and port
server_socket.bind((host, port))

# Listen for incoming connections

# Accept a connection
client_socket, client_address = server_socket.accept()
print(f"Connection from {client_address} established.")

while True:
    message = input("You: ")
    received_message = client_socket.recv(1024).decode()
    print(f"Client: {received_message}")
    if received_message.lower() == "bye":


And here's the code for the chat client:

import socket

# Create a socket
client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
host = ""
port = 12345

# Connect to the server
client_socket.connect((host, port))

while True:
    received_message = client_socket.recv(1024).decode()
    print(f"Server: {received_message}")
    message = input("You: ")
    if message.lower() == "bye":


This code sets up a basic server-client chat application where messages are sent back and forth. The server listens for incoming connections, and once connected, both the server and client can send messages. The chat continues until either side sends "bye."


For Method 1, after running the server and client code, you can see messages exchanged between the server and the client. Here's an example of how the conversation might look:

Connection from ('', 12345) established.

You: Hello!
Client: Hello!

You: How are you?
Client: I'm good. How about you?

You: I'm doing well, thanks for asking.
Client: That's great to hear!

You: Bye
Client: Bye

Method 2: Using Python's Tkinter for a Graphical User Interface (GUI)

While the first method provides a basic chat application, it's entirely command-line based. If you want a more user-friendly experience, you can create a GUI chat application using Python's Tkinter library.

import tkinter as tk

def send_message():
    message = message_entry.get()
    chat_text.insert(tk.END, "You: " + message + "\n")
    message_entry.delete(0, tk.END)

def receive_message(message):
    chat_text.insert(tk.END, "Client: " + message + "\n")

root = tk.Tk()
root.title("Simple Chat App")

chat_text = tk.Text(root, state=tk.DISABLED, wrap=tk.WORD)

message_entry = tk.Entry(root)

send_button = tk.Button(root, text="Send", command=send_message)

# Simulating received messages
receive_message("Hello! How are you?")
receive_message("What's your favorite programming language?")
receive_message("Let's chat!")


This code creates a basic GUI chat application using Tkinter. Users can send messages via the input field and received messages are displayed in the chat window. The receive_message function simulates messages received from the client.

After running the Tkinter-based GUI chat application, you will see a window with a chat interface. You can send and receive messages within the application's graphical user interface.


In this blog, we have walked through the process of creating a simple chat application in Python using various methods. We started with basic socket communication and moved on to a graphical user interface using Tkinter.

By following these methods, you can build a functional chat application and gain valuable insights into network programming, GUI development, and database integration. Feel free to experiment and expand upon these examples to create a more feature-rich chat application.
