Use virtual environments to manage dependencies in Python projects from "summary" of Python For Dummies by Stef Maruch,Aahz Maruch
Virtual environments are an essential tool for Python developers working on multiple projects simultaneously or collaborating with others. When you create a virtual environment for a project, it acts as a separate, isolated space where you can install dependencies specific to that project without affecting your system-wide Python installation. This way, you can avoid conflicts between different projects that require different versions of the same library. To create a virtual environment, you use the venv module, which is included in Python 3.3 and later versions. By running a simple command in your terminal, you can set up a virtual environment directory that contains its own copy of the Python interpreter and standard library. Once you activate the virtual environment, any Python packages you install using pip will be isolated within that environment. This means you can install different versions of the same pac...
