This allows referencing the current version of the unit tests. To clone this repository, run:\n\n```\ngit clone --recurse-submodules https://github.com/rayokota/jsonata-python\n```\n\nTo build and run the unit tests:\n\n```\npython3 -m pip install nox\nnox --sessions tests\n```\n\n## Notes\n\nJSONata date/time functions that use ISO 8601 formats are only supported with Python 3.11+.\n","description_content_type":"text/markdown","docs_url":null,"download_url":null,"downloads":{"last_day":-1,"last_month":-1,"last_week":-1},"dynamic":null,"home_page":null,"keywords":"json, jsonata","license":"Apache License\n Version 2.0, January 2004\n http://www.apache.org/licenses/\n \n TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION\n \n 1.
