If you are talking about Python 2 vs 3, think of them as two separate languages where Python 3 can often use a lot of the libraries developed for Python 2. That makes it all make a lot more sense. Even with that, there was maybe a dozen times in the past 8 years, which is how long I’ve been writing Python code full time, where I felt a problem with the 2 vs 3 thing. They were all quickly resolved. This is unlike Node where things like file access change from version to version, and sometimes shit just doesn’t compile because gyp is of the incorrect version, etc. Node is very high maintenance.
