Have you ever experienced frustration because of the code you wrote? If you have been writing code for a while now, you probably had. And, if not, you certainly will. Sometimes we just keep staring at the code, trying to figure out what it does and why. When we wrote the code, everything was clear, but after a few weeks or months, it looks fuzzy. We can prevent this bad situation simply by writing Python Documentation. In this article, we are going to see how you can use python documentation best practices. These will make your code far more readable and maintainable. Python Documentation Manifesto What does “documenting” mean? Documenting means add information to your code for other programmers to read. If you took coding classes, someone probably told you that writing code means talking to the PC. If you believe that, think again, because computers only understand binary:  0  and  1 . You write code for people to read, not for computers. Let this statement sink in your brai...

Python programming is simple: with only a few lines of code, you can do incredible things. Adopting just the most essential aspects, on the other hand, has a disadvantage: it is difficult to expand. This is not to argue that the software cannot handle large amounts of data; it certainly can. Rather, it means that it will be impossible to expand to a bigger and larger codebase. To put it another way, if you don't start using classes, you'll end up with a jumbled file full of spaghetti code. We'll go over everything you need to know about classes, objects, and instances in this Python Classes Tutorial. With this in mind, you'll be able to write great code in no time.   Table of Contents about Python courses teaching user guide (the easy way) Here’s what we are going to cover today: Python Classes Tutorial: the basics Python Classes are Required Python Classes are now available.

Software-Defined The future of network engineering is being shaped by networking. As a result, everyone in this business will need to grasp how to deal with it. SDN transforms the network into a straightforward service for the application. Any application may need network modifications and evolution, necessitating the creation of progressively complex architectures by engineers. This necessitates the use of SDN software. However, in this article, we will demonstrate how to test the functionality of any SDN software for free. GNS3, a fantastic network simulator, will be used to demonstrate how to test SDN applications. This is helpful if you also want to build software.   Table of Contents about Creating and Testing SDN Software with GNS3 Here’s what we are going to cover today: Why test SDN software? Preparing your PC for connecting to GNS3 Bridging our PC (and the SDN software) to GNS3 Some common problems Conclusion   Why test SDN softw...

SSH is the industry standard for connecting to a network device. This is unsurprising, given that the legacy protocol, telnet, only allows for insecure remote management. Rather than that, SSH stands for Secure Shell for a reason: it is a truly secure protocol that incorporates all modern security features. As a result, we cannot create SDN software without incorporating SSH. We will demonstrate how to use SSH in a Python program to connect to and control remote devices in this Python SSH Tutorial. We will demonstrate how to do things correctly in this article. Are you in a hurry? Simply scroll down for the TL;DR version. SSH encrypts traffic between you and the server, end-to-end.
