Which Python Version to Use?
Some features of Python 3 have been backported to Python 2.x versions to make the migration process easy in Python 3. As a result, for any organization who was using Python 2.x version, migrating their project to 3.x needed lots of changes. These changes not only relate to projects and applications but also all the libraries that form part of the Python ecosystem.
Why should you learn Python 2?
Although, Python 2 is an old open source version here are where you still need to learn Python 2:
To become a DevOps engineer and you need to work with configurations management tools like puppet or ansible. Here, you need to work with both of these versions. If your company’s code written in Python 2, you will require to learn to work with that If your development team is working on a project that depends on specific third-party libraries or software which you are not able to port to Python 3, then Python 2 is the only option available for you.
Why should you use Python 3?
Here, are prime reasons for using Python 3.x versions:
Python 3 supports modern techniques like AI, machine learning, and data science Python 3 is supported by a large Python developer’s community. Getting support is easy. Its easier to learn Python language compared to earlier versions. Offers Powerful toolkit and libraries Mixable with other languages

Which Python Version to Use?
When it comes to Python 2 vs Python 3 differences today, Python 3 version is the outright winner. That’s because Python 2 won’t be available after 2020. Mass Python 3 adoption is the clear direction of the future. After considering declining support for Python 2 programming language and added benefits from upgrades to Python 3, it is always advisable for a new developer to select Python version 3. However, if a job demands Python 2 capabilities, that would be an only compelling reason to use this version.
Summary
Python 2 made code development process easier than earlier versions. It implemented technical details of Python Enhancement Proposal (PEP). Python 2.7 (last version in 2.x ) is no longer under development and in 2020 will be discontinued. Python 3 is a newer version of the Python programming language which was released in December 2008. This version was mainly released to fix problems that exist in Python 2. The nature of these changes is such that Python 3 was incompatible with Python 2. It is backward incompatible. In Python 2, Rules of ordering comparisons have been simplified. In Python 3, Rules of ordering comparisons are very complex. When it comes to Python 2 vs 3 differences today, Python 3 version is the outright winner.
