Posted on Oct 23 If you work on several Python projects, you will quickly need to have different versions of your packages, depending on the current project.Virtual Environments are designed for this, they allow to isolate the libraries between your projects. There are different libraries you can use, I will show you Venv and Pipenv.Venv is the built-in module for creating virtual environments in Python 3.First let’s create a simple script, that needs two packages :Create a file "requirements.txt" :Then you can use this commands (don’t forget to add "venv" in your .gitignore file) :Pipenv is a higher-level tool that combines package management and virtual environment management, using Pipfile.First, install Pipenv :Create a file "Pipfile", made for the script we are working on :(you can also generate it with the "pipenv install" command)Then you can use this commands :Both are good solutions for virtual environments, venv is built-in and lighter to write, also pipenv is faster and allows more possibilities, so choose the good one for the good context.You can also be interested by Pyenv, a complementary tool made to manage different versions of Python on your computer.Templates let you quickly answer FAQs or store snippets for re-use.
