Data Structures & AlgorithmsAbout the TutorialData Structures are the programmatic way of storing data so that data can be usedefficiently. Almost every enterprise application uses various types of data structures in oneor the other way.This tutorial will give you a great understanding on Data Structures needed tounderstand the complexity of enterprise level applications and need of algorithms,and data structures.AudienceThis tutorial is designed for Computer Science graduates as well as Software Professionalswho are willing to learn data structures and algorithm programming in simple and easysteps.After completing this tutorial you will be at intermediate level of expertise from where youcan take yourself to higher level of expertise.PrerequisitesBefore proceeding with this tutorial, you should have a basic understanding of Cprogramming language, text editor, and execution of programs, etc.Copyright and 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.
