Python has always been an exemplar of good coding style for me. It’s impressive how concise unit tests can be, how flexible mocks are. Really, it’s a great pleasure to write Python code. Up until the point when you need to deploy it. From then on you embark on a rollercoaster to go through a variety of tools and approaches. This article is supposed to help you sail over Python dependency hell, stay alive and still enjoy writing in this awesome language.
