DSA in Python – Online Course For Beginners
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 & 24×7 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

Frequently Asked Questions (FAQs)
1. Is Python good for Data Structures?
Being a High-Level and #1 Programming Language, using Python for Data Structure is likely to be among the good choice due to its easy syntax and implementation. Python has an easy learning curve and provides ease for developers, and data scientists to work on different modules such as backend development, machine learning, artificial intelligence, etc.
2. Should I learn DSA in Python or C++?
The more you’ll code, the more you’ll make mistakes and the more you’ll learn. Well, Python is undoubtedly one of the best choices to start with the DSA, but unless you’ll make work on raw structures where inbuild features are not there, you’ll eventually groom up in your logic part.
3. What is the best way to learn DSA in Python?
Start learning the basics of python and then learn about the time and space complexities. After that, you can jump on to the basics of DSA and start practicing the problems on particular topics. To learn more about this you can refer to the Complete Roadmap to DSA.
4. How long does it to learn DSA in Python?
It would require consistent practice and dedication and solving as many problems as you can. It should take anywhere between 3 to 6 months to learn DSA right from the scratch with the help of quality resources and proper guidance. Also, it totally depends on how much time you are giving per day and basics are cleared or not.
Being on a beginner’s level will definitely give a kick start while working with the Data Structure and Algorithm. The concepts, structure, and methods are so intuitive that you’ll soon be ready for advanced-level programming with Python. The best part is its Live Lecture, practice questions, Certificate, and Interview Preparation that will create a smooth journey in Data Structure with Python. All you need is to be consistent and Practice as much as you can.
