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. This release is the sixth of seven planned alpha releases before Python enters the beta phase, which is scheduled for May 5, 2022. PEPs now have a new home with a sleek, modern theme. Also, PEP 594, which deals with removing dead batteries from the Python standard library, has been accepted. Regarding Python events, EuroPython 2022 […]

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 […]

Python has a lot of GUI frameworks, but Tkinter is the only framework that’s built into the Python standard library. Tkinter has several strengths. It’s cross-platform, so the same code works on Windows, macOS, and Linux. Visual elements are rendered using native operating system elements, so applications built with Tkinter look like they belong on the platform where they’re run. Although Tkinter is considered the de facto Python GUI framework, it’s not without criticism. One notable criticism is that GUIs […]

Django has a Paginator class that comes built in and ready to use. Perhaps you have a project on the go, and you’d like to try out the pagination implementations in the following sections with your app as your base. No problem! However, if you want to follow the step-by-step code examples in this tutorial, then you can download the source code for the Django Python wiki project from the Real Python materials repository: This wiki project contains an app […]
