Clone/copy python file

We are using Databricks extensively in the company. We found out that we can’t clone/copy *.py file using UI. We can clone notebooks but not python file. If we clone folder, we only clone notebooks inside folder but not python file.

@shiva1212  When working with Databricks and managing Python files, it's true that the UI limitations can sometimes be restrictive. you can use Databricks CLI and REST API for file management and copying.

Hi @Mangeysh,You could achieve this using Databricks SQL Statement Execution API. I would recommend going through the docs and looking at the functionality and limitations and see if it serves your need before planning to develop your own APIs.
