The Real Python Podcast Tools for Setting Up Python on a New Machine
Leave The System Python Alone
- System Python is for the OS and should be left untouched to avoid breakage.
- Beginners commonly cause long-term messes by installing packages into the system interpreter instead of per-user environments.
Multiple Pythons Cause Hidden Breakage
- Multiple install methods lead to opaque environments and 'works on my machine' problems.
- Knowing PATH and virtual environment state is essential to avoid accidental cross-contamination.
Use A User-Level Package Manager
- Install tooling with a user-level package manager instead of using sudo or system Python.
- Use Homebrew (mac/Linux) or Chocolatey (Windows) to avoid root installs and keep environments isolated.
There are many ways to get Python installed on your computer. If you were going to start fresh, what tools would you use? What if you need to manage multiple versions of Python and virtual environments? What about all the additional tools that make your coding workflow complete? This week on the show, Calvin Hendryx-Parker is here to talk about bootstrapping your Python environment.
Calvin is the co-founder and CTO of Six Feet Up and a Python Web Conference co-organizer. As a consultant, Calvin has set up countless machines to run Python. He configures environments that can scale from in-office projects to distributed cloud-based applications.
We cover tools for installing Python, managing multiple language versions, and configuring virtual environments. Calvin talks about setting up command-line applications in isolated environments. We also discuss traveling with Python on an iPad.
