Although this version is supposed to be backwardincompatibles, later on many of its important features have been backported to becompatible with the version 2.7. This tutorial gives enough understanding on Python 3version programming language. Please refer to this link for our Python 2 tutorial.AudienceThis tutorial is designed for software programmers who want to upgrade their Python skillsto Python 3. This tutorial can also be used to learn Python programming language fromscratch.PrerequisitesYou should have a basic understanding of Computer Programming terminologies. A basicunderstanding of any of the programming languages is a plus.Execute Python ProgramsFor most of the examples given in this tutorial you will find Try it option, so just make useof it and enjoy your learning.Try the following example using Try it option available at the top right corner of the belowsample code box #!/usr/bin/python3print ("Hello, Python!")Copyright & Disclaimer Copyright 2016 by Tutorials Point (I) Pvt.

site "Python 2.x is legacy, Python 3.x is the present and future of the language". In addition, "Python 3 eliminates many quirks that can unnecessarily trip up beginning programmers". However, note that Python 2 is currently still rather widely used. Python 2 and 3 are about 90% similar. Hence if you learn Python 3, you will likely

There are currently two versions of Python in use; Python 2 and Python 3. Python 3 is not backward compatible with Python 2. A lot of the imported modules were only available in Python 2 for quite some time, leading to a slow adoption of Python 3. However, this not really an issue anymore. Support for Python 2 will end in 2020.
