Upgrading projects is somewhat equivalent to flossing, you know you have to do it, but rarely make time for it. After all, if the project is in active development, there are exciting new features to build. And we all know that new features > project upgrades. Well not to worry, Caktus wants to make you aware of some tools that will save you from considerable repetitive work & time while simultaneously modernizing your codebase. Combined, these tools will automate part of the upgrade process, decreasing the likelihood of neglecting parts of the codebase.
Switch to f-strings with flynt
flynt is a tool to automatically convert a project's Python code from old "%-formatted" and .format(...) strings into Python 3.6+'s "f-strings".
