I was asked about a seemingly simple line of code in one of my scripts and I didn't have an immediate answer. After a few pages of g-search, I'm still a bit stumped, but not afraid to ask for the answer!
facFC = arcpy.CreateFeatureclass_management("in_memory", "facFC", "POINT")
What exactly is the  at the end of this statement for?
There's examples of having it there and other examples it's not found.
