In this tutorial, you’ll learn how to work with Python’s venv module to create and manage separate virtual environments for your Python projects. Each environment can use different versions of package dependencies and Python. After you’ve learned to work with virtual environments, you’ll know how to help other programmers reproduce your development setup, and you’ll make sure that your projects never cause dependency conflicts for one another. Virtual environments are a common and effective technique used in Python development. Gaining […]

In March 2022, the Python 3.11.0a6 pre-release version became available for you to test, so you can stay on top of Python’s latest features.

If you’re writing software to process data, you will often hit performance problems: batch jobs that run too slowly, or use too much memory. One potential solution is purchasing better hardware. With cloud computing, switching to a computer with more cores, or adding more RAM, can be done in a few minutes, or even just a few seconds. But as with any solution, there are tradeoffs involved. If your first solution to any performance problem is spending more money on […]

Building a site connectivity checker in Python is an interesting project to level up your skills. With this project, you’ll integrate knowledge related to handling HTTP requests, creating command-line interfaces (CLI), and organizing your application’s code using common Python project layout practices. By building this project, you’ll learn how Python’s asynchronous features can help you deal with multiple HTTP requests efficiently. In this tutorial, you’ll learn how to: Create command-line interfaces (CLI) using Python’s argparse Check if a website is […]

Python is often marketed as a batteries-included language because it comes with almost everything you’d ever expect from a programming language. This statement is mostly true, as the standard library and the external modules cover a broad spectrum of programming needs. However, Python lacks built-in support for the YAML data format, commonly used for configuration and serialization, despite clear similarities between the two languages. In this tutorial, you’ll learn how to work with YAML in Python using the available third-party […]
