For Python development, we mainly focus on IDE, browser and sometimes a command line. I want to focus on command line tools which seem to be a bit forgotten these days. Let me show a few tools I'm using on daily basis and how they helped me become more productive. I'll prove it's possible to start up a new environment from scratch that feels like $HOME. Finally, I want to convince you how important it is to constantly challenge yourself and your tools, how useful is a custom toolbox tailored to you.
