Data Structures Using Python

In computer science a data structure is a data organization management and storage format that enables efficient access and modification. More precisely a data structure is a collection of data values the relationships among them and the functions or operations that can be applied to the data.Data structures serve as the basis for abstract data types (ADT). The ADT defines the logical form of the data type. The data structure implements the physical form of the data type.Different types of data structures are suited to different kinds of applications and some are highly specialized to specific tasks. For example relational databases commonly use B-tree indexes for data retrieval while compiler implementations usually use hash tables to look up identifiers.
