1. Introduction An operating system (OS) is a software program that manages the hardware and software resources of a computer system. The OS is responsible for managing the computer's memory, processing power, storage, and input/output devices. It also provides a user interface that allows users to interact with the computer and run applications. In this blog post, we'll explore the history of operating systems, the types of operating systems, the functions of operating systems, the components that make up an operating system, virtualization and containerization, security considerations, and the future of operating systems.

  What is Software Testing? Software testing is a crucial process in software development that ensures that software is free from defects, meets user requirements, and performs as expected. In today's fast-paced world, software testing has become even more important because of the growing demand for high-quality software that is delivered on time and within budget. In this blog, we'll explore the various types of software testing, the software testing process, the benefits of software testing, common tools and techniques used in software testing, and steps to learn software testing. Why Software Testing is important? Testing helps identify bugs and errors in software before it is released to users. It is a critical step in the development process, ensuring that the software meets the requirements and functions as intended. Additionally, testing helps prevent downtime and ensures that users have a positive experience with the software.

  9. Real-World Examples and Demo Scripts in Selenium Automation We will provide real-world examples and case studies to showcase the application of these best practices in practical scenarios. This will help you understand the implementation of these techniques in real automation projects. 9.1. Launch Selenium Practice Form Script This demo script will open the Chrome browser and open the selenium.dev website. from selenium import webdriver browser = webdriver . Chrome( "chromedriver.exe" ) browser . get( 'https://www.techlistic.com/p/selenium-practice-form.html' ) 9.2. Search the keyword "Selenium" in the pypi.org search box In this script, we'll launch Chrome browser, open pypi.org, and then type ""Selenium" in the search bar and will click enter. from selenium import webdriver from selenium.webdriver.common.by import By from selenium.webdriver.common.keys import Keys # Launch Chrome browser browser = webdriver .

1. What are Modules in Python? In Python, a module is a file containing Python code. It can be a Python file (with .py extension) or a compiled Python file (with .pyc extension). It contains functions, classes, and variables that can be used by other Python programs. Modules help us to organize our code into separate files, which can be used in other programs, making our code more reusable.
