What is data structure?

It is the collection of data and it is a way to organize data in a computer and can be used in a different way.

What is python?

Python is a high level programming language and is easy to understand. It syntax can be understand easily as compare to other languages.

Download data structures and algorithms with python. These notes are very easy to understand and provide much information to its users. Through these notes you can learn how to handle a data by different steps and give you idea about algorithm which helps you in writing your own programs. These notes will give you the tool to determine that how efficient an algorithm is which helps you to in making judgments about any of the programme you write. In these notes, the start of every chapter contains the goals and in the end review questions about the reinforcement of the goals are stated. There are a lot of examples also stated for the better understanding of the reader. You can easily download these notes without any cost.
