Python 3. The 2 vs 3 era ended quite some ago. Most major operating systems that aren't end of life have Python 3.6+ installed by default giving you access to nice things like f-strings. A lot of Python 2.x scripts will work with Python 3. If they don't then it's on you to fix them since Python 2.x was officially labeled end of life almost 2 years ago from today. On the bright side, your Python 2.7 script had a good run. 2.7 was released back in 2010, so having ~10 years of not having to worry about anything is pretty good! Chances are we'll get the same experience or longer with Python 3.6+, we already at the 5 year mark for Python 3.6.
