Not sure still what caused the issue, but disabling and then re-enabling the Pylance extension has solved this.  Thanks.
On hovering the mouse pointer over a function, whether inbuilt or custom, the definition and docstring of the function shows as expected, however it shows twice.  I have had a search for what might be causing this and looked around my settings, but have yet to find a reason for it.  If it makes a difference, am using Python on VSCode.
Perhaps someone knows what might be causing this and how to resolve?  I have not attached any images, since I think the issue is quite clear, but happy to provide if needed for clarification.
Thanks!
Why does the function definition and doctring show twice when I hover over the function in VS Code? How to resolve to showing once?
