For this reason I’ve decided to create a post that lists the most important tools, when and why they are used and what problem they solve. I will try to explain with simple words how you should approach each one of these tools. If a tool is here, it means that, as a Python programmer, you’re supposed to at least know its existence. I will list only tools that can be applied to any project or workflow and that you should consider every time you start a new project. This doesn’t mean you always have to use each one of them on every single project. Too much tooling can be easily be an overkill and become hard to maintain in some cases.
