Sockets
Let’s talk about the basics of socket programming. Its use can range from setting up a connection to transferring data between two systems through to more complex topics such as threading, getting stuck into network protocols and serverless computing.?
Engineers can use sockets to build robust communication solutions using Python, using either built-in Python features or libraries like Socket.IO.
The low-down on sockets
Sockets are low-level networking tools used to establish connections between two systems. They're built using the Python socket module, which provides basic operations like connecting, listening, and sending data.?
Sockets can be used to create client-server applications. By using sockets, engineers are able to avoid manually writing code for every connection.?
We can implement a wide range of communication protocols such as HTTP, FTP, and SMTP. By using low-level sockets, you can even create your own custom communication protocol or use existing ones to build complex network applications.?
Sockets give you full control over how information is exchanged between two nodes in a distributed system. This makes it ideal for creating powerful applications that need to handle large amounts of data and communicate between multiple computers. Additionally, as Python is a high-level language, you can abstract away much of the complexity associated with handling and using sockets, making it easy to use them in your application.?
Socket.IO and Python Sockets
When working with Python sockets, engineers can take full advantage of the low-level protocol interactions that come from utilising raw sockets.

This can be especially useful when dealing with third-party APIs or custom protocols that require specific headers or functions which are unsupported by Socket.IO (or any other socket libraries for that matter.)?
Additionally, Python sockets allow engineers more control over how they manage their network connections and related activities due to its flexible usage capabilities.?
But Socket.IO comes with a range of ready-to-go features, offering several helpful features over plain sockets, such as automatic reconnection and support for broadcasting messages to multiple connected clients.?
Socket.IO makes it easy to create robust message routing infrastructure with features like namespaces and rooms that allow you to send messages to specific groups of users or perform selective filtering on incoming messages.?
So whilst Python sockets offer great flexibility and control to developers, Socket.IO is a feature-rich library that’s waiting for you. Check them both out and choose your direction based on what you need.?
Here’s a quick look at a simple socket application showcasing connecting to a server. Not too bad, huh? Though, uh, you should probably have some error handling in there. Sparks students, and, well, any student! How would you improve it? :)
import socket
our_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
print ("Socket successfully made! Nice.")?
port_num = 80
remote_ip = socket.gethostbyname('www.sparkscreate.com')
our_socket.connect((remote_ip, port_num))
print ("We have successfully connected to Sparks!")
Summing up?
Sockets allow engineers to create powerful networked applications quickly.?
By understanding how to make use of sockets in Python, engineers are able to produce efficient solutions that allow inter-system communication without having to manually write code for every connection. Pretty nice.
