[MridulS]

[Everyone can do this task. There is no need to claim/assign this issue]

Make sure you have completed the first task before proceeding further. In this task applicants are expected to setup their local development environment, required to contribute code to the networkx project. Applicants should go through our Contributor Guide.

Once you have installed all the requirements and setup the environment, please run the tests locally. If all the tests pass then copy the output of $ PYTHONPATH=. pytest networkx and put it inside a file named nx_dev_test_output.txt. Add this file to your folder created in the first task and push the changes to github.

Create a pull request against this repository and add the file 2023-round-2/<your-github-username>/nx_dev_test_output.txt with the pytest output.
