Yeah, true.

I think the consensus is now that the OP is using some kind of IDE where the IO 
streams are not connected to terminals or other real OS-level files, but to 
stream abstractions delivering the the IDE display widgetry. Thus no .fileno() 
facility, because there is no OS-level file.

But we have yet to obtain that information from the OP.
