Dependency hell stands as one of the most infamous aspects of developing in Python. Suffer through enough situations of broken packages clashing across projects and you quickly appreciate the necessity of virtual environments.
Thankfully Python itself comes packaged with the venv module to isolate environments per project. And the external virtualenv tool recently introduced massive improvements for managing virtualenvs across interpreters and operating systems.
In this guide specifically for Python beginners, you’ll learn:
- Why virtual environments help all Python projects
- Creating venv virtualenvs
- Using pip with isolated deps
- New capabilities unlocked with virtualenv
- Structuring projects for multi-environment support
Let’s dive in to simplify your Python development environment!
Why Isolate Project Dependencies?
Most languages clearly separate reusable dependencies vs core application code. In Python, it’s common to just install packages globally.
