Hello,

would like to suggest you here

It sounds like you may have accidentally enabled "Python Mode" in Jupyter Notebook, which is a feature that provides syntax highlighting and autocomplete for Python code.

To disable Python Mode and restore the default Jupyter Notebook behavior, you can follow these steps:

1. Open Jupyter Notebook in your web browser.
2. Click on the "Edit" menu at the top of the screen.
3. Select "nbextensions config" from the dropdown menu.
4. In the nbextensions configuration page, find the "Python Mode" extension and uncheck the box next to it.
5. Click the "Save" button to apply the changes.
6. Restart your Jupyter Notebook kernel for the changes to take effect.

After following these steps, you should be able to use the default Jupyter Notebook keyboard shortcuts and autocomplete features. hope so it will help you . Novitasphere MBI Lookup Tool
