Building a Website Connectivity Checker with Python

Knowing whether a website or API is online is a fundamental requirement for many automated workflows and monitoring systems. Building your own reliable connectivity checker is the perfect way to master real-world Python scripting. Through this text-based course, you will transition from writing basic scripts to developing a structured, modern Python utility. You will learn to manage dependencies cleanly, handle network requests safely, and implement concurrent checks to monitor multiple sites at once. What you'll learn: Understand the fundamentals of HTTP status codes and network requests in Python; Configure clean Python virtual environments and manage project dependencies modernly; Build a command-line utility that checks website connectivity and handles timeouts gracefully; Apply modern type hints to ensure your Python code is readable and robust; Implement asynchronous programming concepts to check multiple websites concurrently; Practice writing basic tests using pytest to verify your checker works as expected. The course starts with foundational networking concepts and environment setup before guiding you step-by-step through writing, refactoring, and testing your connectivity checker. This course is designed for beginner Python developers who want to build practical automation tools, and no prior networking experience is required.
