Python Versions and Dependencies Made Easy

Development Tooling Virtual Env

See in schedule

Managing Python versions and dependencies can be painful. JavaScript developers have their "node_modules" folders, but we don't have "python_modules" (yet!) in Python. Instead, we have those mysterious virtual environments. And if you also want to switch between different Python versions, it can quickly turn into a mess.

It doesn't have to be that way. With a few simple tools and practices, you can easily tame Python and its dependencies. In this talk, I'm going to show you how to do this.

I will talk about:

* How to manage Python versions with pyenv and set different versions for a folder or a shell session?
* What are virtual environments, what's the difference between different tools (venv, virtualenvwrapper, conda, etc.), and how to use them?
* How to separate global packages with pipx (and why you should do this)
