Deleting multiple feature classes using the ArcPy Delete function fails with the error message, "RuntimeError: Object: Error in executing tool."

Workaround

The Delete tool fails with ["a", "b", "c"] but succeeds with ["a;b;c"]. As a workaround follow the steps below:

## Use ListFeatureClasses with wildcard to obtain a list of feature classes to be deleted

fclist = arcpy.ListFeatureClasses(...)

arcpy.management.Delete(";".join(fclist))

​

This works in Python IDLE and standalone script, but does not work in the Python window of ArcGIS Pro.
