Checking selection state on Featurelayer

Question

I need to write script that changes some attributes for selected features.
Is there any way to chceck if featurelayer represent selection? Cause now when I'm using layer without any selection it changes attribiutes for all features and that not exactly what I want. 😞

Run a gp.Describe(layer) and you can get out the Layer properties FIDSet. This is a clumsy string of all the FIDs that are in the selection. But it enables you to get a list of which features are selected.

Thanks, that solves my problem 🙂

Use arcpy.GetCount_management() to check if the layer has a selection.
It will report back how many records are selected (if any).
