После долгих исследований я выяснил, как манипулировать листом Ubuntu LibreOffice Cal c, используя Python 3.7, PyCharm и MySQL. Я новичок ie во всем этом, поэтому, пожалуйста, извините за мой код, я все еще учусь. Я предоставил ссылки на источники информации, которые я использовал для завершения этого проекта.
Основным камнем преткновения, который вызывал у меня проблемы, было отсутствие понимания того, что офис Libra необходимо было инициировать до подключения через сокет. После этого я смог использовать Uno и другие модули для взаимодействия с электронной таблицей Cal c. Я предоставил копии всех моих скриптов Py. Надеюсь, это поможет всем, кто любит меня, новичок в этой среде.
