We all must have learned in school that a program needs instructions to perform any dedicated task such as sequencing a number, sorting tables, etc. However, these tasks are required to store, retrieve, and perform to form a symmetric structure in the virtual system. In other words, a data structure is used to perform all these actions (store-retrieve-organize) data in a structured way with the help of algorithms in an efficient manner.

Now, to learn DSA, you need to learn at least one programming language and python is the best choice nowadays. As per reports, Python was voted as the #1 Programming Language among Java, C/C++, etc. Not only this, currently there are more than 32,000 jobs available for Python Developers (in India) & 134,000+ (worldwide), and that's why people are inclined towards Python Programming Language.
Why DSA with Python?
As we know that Python is a beginner's Language and is used in machine learning, game development, artificial intelligence, web development, etc. Python is a simple, high-level, general-purpose programming language that offers easy syntax and was introduced with the concept of providing ease of learning (just like English).
Built-in Data Structures in Python
Built-in Data Structures are the data types that cover almost every part of real-world DS and are directly used by developers (for both storing and declaring) different variables within a program. There are 2 major categories i.e. Primary (Primitive) and Non-Primitive (Lists, Dictionaries, Tuples, and Sets) Data Types.
If you're looking to master DSA using Python Programming Language and prepare for big tech giants, we recommend you enroll yourself in Data Structure & Algorithms in Python - Self-Paced Course, designed to offer video tutorials, and a lot of practice sets and too with course completion certificate & 24x7 doubt support assistance.
User-Defined Data Structures in Python
Since data management (including organizing and sorting) in a logical manner is being handled into Data Structure, the stored data supports two kinds of data i.e. Primitive & Non-Primitive Data Types. However, it is also abbreviated as UDT which helps in extending built-in data types so that customized data types can be created.
Besides this, there are six major methods of implementing the same, those are:
- Linked List
- Stack
- Queue
- Tree
- Graph
- Hashmap
This DSA with Python course has been curated to take you forward from the basics of data structure to the advanced level with concepts like Lists, Strings, Graphs, Hash, etc., and is suitable for both beginners and advanced-level programmers. This self-paced course will also drive through effective methods of appearing for top-notch Product based companies (such as Amazon, Netflix, Microsoft, etc.)
