@ccc Hi, it doesn't worry me too much because I think I will continue to use my personal Python 2 scientific scripts (for work and hobby) that usually don't require any Python 3 features, but I have often asked myself some questions that I have never been able to answer.
Really I never understood why it was useful to develop a different version of Python (why create a new big version of Python, from 2 to 3, instead to give Python 2 the same useful features of Python 3? maybe too complicated the upgrade of the existing Python 2 and more easy the develompment from zero of a new programming language that is Python 3?).
Has Python 3 started to be developed due to several requests by users about usage of Python 2 programming language? I mean, what had prompted developers to start creating Python 3 instead of upgrading Python 2 with the additions (new/different features) requested by users that now are implemented in Python 3?
Was it not enough to modify Python 2 with the purpose of interpreting the new Python 3 syntax, in order to have Python 2 updated with the most interesting things provided for Python 3?
And apart from some syntax differences between Python 2 and 3 (for example the different syntax of the "print" function), what features are really more efficient in Python 3 to justify the abandonment of Python 2, and the consequent abandonment of innumerable Python 2 libraries which are no longer updated to Python 3 by the developers?
Bye
