Selecting a version of Python to use

This is a classic battle among Python developers—Python 2.7.x or Python 3.x—which is better? Until a year back, it was Python 2.7.x that topped the charts; the reason being it was a stable version. More than 70% of projects used Python 2.7, in the year 2016. This number began to fall and by 2017 it was 63%. This shift in trends was due to the announcement that Python 2.7 would not be maintained from January 1, 2018, meaning that there would be no more bug fixes or new releases. Some libraries released after this announcement are only compatible with Python 3.x. Several businesses have started migrating towards Python 3.x. Hence, as of 2018, Python 3.x is the preferred version.
