"It Makes the Code Clearer": Why Developers Adopt Modern Python Features in Open Source Projects

This dataset accompanies the study “It Makes the Code Clearer: Why Developers Adopt Modern Python Features in Open Source Projects.” It contains the tools, scripts, and data used in the quantitative and qualitative analyses presented in the paper.

• BooksCodes.xlsx — Qualitative results spreadsheet: contains the 77 coded excerpts (quote substrings) and their assigned themes/categories from the manual thematic analysis.

• github_api_scrapper-master.zip — Python-based infrastructure used to collect pull request comments from GitHub’s REST API and assemble the raw qualitative corpus.

• PullRequestCommentsDataset.xlsx — The final set of 494 manually verified pull request comments discussing Python source code rejuvenation, including repository identifiers and coding metadata.

• PyMiner-develop.zip — The PyMiner tool used to mine the source code history of 424 GitHub repositories, parse ASTs to detect modern Python features, and emit project-level CSV outputs.

• pyminer-postgres-backup.sql — PostgreSQL dump of the full raw PR-comments corpus (~395,702 comments) and related tables (schema, data, constraints). Suitable for restoration via psql (e.g., psql -U <user> -d <db> -f pyminer-postgres-backup.sql).

All materials are provided to support replication and further research on source code rejuvenation and language feature adoption in Python.
