ArcMap 10.5.1
In Problems with an Update Cursor I noted that I received an error upon running an update cursor on a table view. I just ran it again and got:
Runtime error
Traceback (most recent call last):
File "<string>", line 10, in <module>
RuntimeError: The operation is not supported within an edit session.

I suspect my lack of experience with update cursors is the root cause; I ran it in an edit session in ArcMap to get the error. I don't get the error outside of an edit session.
For some reason, I thought update cursors needed to be run in an edit session: is that not the case?
