New Year 2020 marks the end of more than a decade of coexistence of Python 2 and 3. The Python landscape has changed considerably over this period: a host of new tools and best practices now improve the Python developer experience. Their adoption, however, lags behind due to the constraints of legacy support.
This article series is a guide to modern Python tooling with a focus on simplicity and minimalism.¹ It walks you through the creation of a complete and up-to-date Python project structure, with unit tests, static analysis, type-checking, documentation, and continuous integration and delivery.
This guide is aimed at beginners who are keen to learn best practises from the start, and seasoned Python developers whose workflows are affected by boilerplate and workarounds required by the legacy toolbox.
On Windows 10, enable the Windows Subsystem for Linux (WSL) and install the Ubuntu 18.04 LTS distribution. Open Ubuntu from the Start Menu, and install additional packages using the following command:
sudo apt update && sudo apt install -y make build-essential libssl-dev zlib1g-dev libbz2-dev libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev libncursesw5-dev xz-utils tk-dev libffi-dev liblzma-dev python-openssl git
In this first chapter, we set up a Python project using pyenv and Poetry. Our example project is a simple command-line application, which uses the Wikipedia API to display random facts on the console.
Here are the topics covered in this chapter:
