Hello slicer developers,  
How to get the slice view (Red, Green or Yellow) under the mouse cursor in Python, like what shown in Data Probe module (Eg: Green in the image)?

And also how to get the plane coordinates (or plane equation) of the current slice view, so that i can set the plane to that slice view later when a button is clicked.

See examples in the [script repository](https://slicer.readthedocs.io/en/latest/developer_guide/script_repository.html#get-current-mouse-coordinates-in-a-slice-view). You can get the slice normal from the [SliceToRAS](https://apidocs.slicer.org/master/classvtkMRMLSliceNode.html#a888f4614c00f350f4440ac9bde8a3a6d) homogeneous transformation matrix (slice normal in the RAS coordinate system is the third column of the matrix).
