Python has two major versions, which are updated separately. These versions are Python 2 and Python 3. Common Python users often find themselves in doubt about these versions. In continuation and considering new users, a brief discussion is presented here.
Both versions
Although Python has two different versions, to the average user, there are essentially no fundamental differences. In most cases, the structure and functions remain the same, with only minor differences. Therefore, instead of new users worrying about which version to use, it is better for them to focus on learning Python.
Version 2.X
Currently, this version is virtually obsolete. Only those who have previously worked with it and have not updated to the newer version still use it. Many packages do not support the 2.X version. If you are a completely new user, it is best not to use this version.
Version 3.X
This is the latest version of Python. New users should start learning this version without considering anything else. Any type of application, such as deep learning, machine learning, software development, big data analysis, etc., uses this version 3.X. It goes without saying that eventually, the 2.X version will be discontinued, leaving only 3.X.
Personal Opinion
I always say that the programming language is not a big issue. Similarly, which version of a language to use is also not a big issue. Once you know one, learning another takes very little time. In the context of this post, I would say – if someone wants to learn Python, there is no question of using any version other than 3.X.
