Project Description

Currently, the aim of the project is to be a Python package for various data structures in computer science. In addition, we are also working on including parallel algorithms. To the best of our knowledge there doesn't exist any well designed library/package which has covered most of the data structures and algorithms including their parallel implementation. We are using Python because, the software development can happen at a much faster pace and it is much easier to test various software designs and APIs as coding them out takes no time.

In future, i.e, after a few releases of the package when the software design will become stable, we also aim to provide APIs for the code in C++ and Java as well. For clarity, the interested students aren't expected to know C++ and Java. Knowledge of Python is enough for this project.

The students who are interested to work on this project will implement various data structures and algorithms, during the duration of the program, from scratch. For more details see, Tasks and features.

Learning Outcomes

The students will learn the following aspects of software engineering,

  1. Software design - Before starting coding out any data structure, we have a practice of discussing the use cases and designing APIs for that. This will make students learn the importance of designing stable software.
  2. Writing clean code - We follow numpydoc string guide for our documentation and PEP 8 guidelines which results in a really clean code and helpful for future developers. This will inculcate a habit in students to write clean code.
  3. Testing and coverage - Since we implement data structures writing tests to increase code coverage is most important to us. This will help students learn how to write tests and covering corner cases.

Mentors and Coaches
Our project will give the students an experience of how software development pipeline works.

The following remote coaches will be there to help the students during the program,

  1. Gagandeep Singh
  2. Vedansh Priyadarshi

We have also participated in KWoC, 2019 organized by KOSS, IIT Kharagpur , amDeC, 2019 organized by amFOSS, Amrita Vishwa Vidyapeetham, Amritapuri and JMOC, 2020 organised by JIIT Noida.
We have also been accepted GirlsScript Summer of Code, 2020. Though if the timelines of RGSoC, 2020 and GSSoC, 2020 clash then we will make special arrangements for allocating issues to the participants of both the programs equally by attaching special labels like, rgsoc2020 and gssoc2020 for separation.

Project's Requirements

Students should have the following skills,

  1. Familiarity with Data Structures and Algorithms, either through course work or sports programming.
  2. Some experience with Python. Sharing your projects in Python programming language will be helpful for us to provide you resources accordingly.

Tasks And Features

The list of tasks which the students will perform is as follows,

Implementing Data Structures
We want students to implement various types of heaps. Currently, BinomialHeaps and BinomialHeap are supported by the package. Some specific types which aren't implemented yet are as follows,
1. FibonacciHeap - Details are given at
2. TernaryHeap
3. PairingHeap

The above is just a tentative list, more can be added according to the requests received.

We also want students to implement various trees, like,
1. KDTrees - The details are given at
2. FenwickTree -
3. SplayTree
4. RedBlackTree

Implementing Graph Algorithms
Some of the algorithms for Graphs which are to be added,

  1. BreadthFirstSearch - Both serail and parallel version of this algorithm. The details are given at
  2. DepthFirstSearch - Both serial and parallel version.
  3. DeepWalk -

Some easy to fix issues are available at

Some of the core issues are also required to be fixed, for example,
1. Creating customised version of deepcopy for our package -

We again state that the above is just a short tentative list of tasks. We can change the road map according to the participants' interest. However, the plan of action for including any new API is fixed and is available at

We are Shalini Negi and Tanuja contributing to this project.
Tanuja ans Me are very enthusiast for data structure ans algorithms.
We have implemented fen wick tree, SplayTree and other data structure in c++ and java.
It will be very great and interesting for us to impalement theses in python.
Both of us are willing to learn Vue and Django. We are interested as well as excited to work on this project. Looking forward to getting further guidelines.

Hello! This is Sukriti Shah and Samruddhi Nirali - Team codingDuo , this side. We found this project pretty interesting. We are currently going through the codebase. We would love to start contributing as soon as we can. Thank you!

Tushika25, Sunday, March 29, 18:33 UTC

This is Tushika Singh from the team "Naam mein kya rakha hai" from Mandi, India. Me and my team mate are interested in doing contributions in the Fibonacci heap and are looking forward for your help so that we could get an idea of how we can create a separate library which could inculcate the various heaps required (we would code them all individually and pack them all together later). Thus, I look forward that you could guide us on how things can be done once we get the basic knowledge on the content required to code.
I had mailed regarding the same but didn't get any response.
Hoping to work on this wonderful project.
Thank you

Hi Anagha,

Yes you can create issues for project ideas related to data structures and algorithms.

Anagha Mittal, Friday, March 13, 19:52 UTC

I am a participant in RGSoC 20 and would like to work on this project. My query is whether we can create an issue for the existing website or just strictly have to stick to the topic decided for this year.

Gagandeep Singh, Wednesday, March 11, 16:56 UTC


I would like to clarify a few things for the participants interested in this project for RGSoC, 2020 through this message.

As per this tweet the official working period starts from July, so making contributions isn't a necessity till your acceptance to the program. For getting accepted, you have to submit your application as described in the steps given at this link before 31st March, the official deadline.

For now, you can discuss the API designs of the data structures and algorithms you want to work on once the working period starts. You can also discuss with me if you are having some new ideas in the areas of data structures and algorithms. My contact information is given at the end of the project description. Vedansh Priyadarshi will be the remote coach for this project.

Please feel free to ask your doubts/queries.

Best wishes.

Hi Riya,

If you are new to open source then you can start with easy to fix issues like improving documentation, adding tests and fixing some trivial bugs, improving code quality. For some examples, see some easy issues on our repository.

For the summer projects, we have opened some issues for RGSoC, 2020. See, Though these are just ideas, you can propose your own by opening new issues. See, list of data structures and pick any which you want to add to PyDataStructs.

Feel free to ask your doubts/queries.
