I'm pretty sure Twisted(!) did not have Python 3 support 5 years ago. Also, macOS _still_ only ships with Py2. If I'm writing a quick script for my girlfriend to make her life easier, should I target Python 3 and force her to learn how to install xcode so she can learn to use homebrew so she can install Python 3, or should I just target Python 2 and move on?
