Python is one of the most popular programming languages in the world, valued for its simplicity, versatility, and the vast ecosystem of tools and libraries it supports. Whether you’re diving into data science, automating mundane tasks, or experimenting with cutting-edge image and video generation tools like ComfyUI, Flux LoRA Trainer, and Face Swap tools, Python is a must-have skill. In this guide, we’ll walk you through the step-by-step process of installing Python on your preferred operating system—be it Windows, MacOS, or Linux.

I. Introduction

Python powers everything from artificial intelligence to web development. Its increasing relevance in media-related applications is remarkable, particularly with tools like ComfyUI for custom image generation, LoRA Trainer for fine-tuning AI models, and Face Swap tools for creating advanced video effects. With Python, the possibilities are endless.

This guide will equip you with all the knowledge needed to install Python and get started on your programming journey, whether for personal or professional projects.

II. Choosing the Right Python Version

Python 2 vs Python 3

While Python 2 was once a dominant choice, support for it officially ended in 2020. Python 3 is now the standard and includes features and improvements that make coding more efficient. Unless you’re maintaining legacy projects, Python 3 is the version you should choose. To find the Python version requirement, refer to the AI tool creator’s website or GitHub page. For example, ComfyUI’s official GitHub page stipulates that Python version 3.12 is required!
