Summary by cubic

Import the langchain-daytona-data-analysis package to add DaytonaDataAnalysisTool for running Python data analysis in a secure, persistent Daytona sandbox. Adds file handling, pip installs, optional result callbacks, and ships with docs, a notebook, and tests.

• New Features

  • DaytonaDataAnalysisTool: run Python in a persistent Daytona sandbox; auto-prints the last expression when print(...) is missing.
  • File ops: upload, download, remove; tool lists uploaded files in its description.
  • Sandbox control and packages: install_python_packages(...), get_sandbox(), close().
  • Optional on_result callback for ExecutionArtifacts (stdout, charts).

• Dependencies

  • New package at packages/langchain-data-analysis published as langchain-daytona-data-analysis.
  • Runtime deps: daytona ^0.113.2, langchain-core >=0.3.15; Python >=3.9.
  • CI: pin to Python 3.12 for obstore wheels (transitive via daytona).
  • Auth via DAYTONA_API_KEY or pass daytona_api_key.
