One way to verify that is to run 

$ cat tmp.py
d = dict(a=1, b=2)
x = d.items()
y = d.iteritems()
z = d.viewitems()

through the 2to3 tool:

$ 2to3 tmp.py 2> /dev/null
--- tmp.py      (original)
+++ tmp.py      (refactored)
@@ -1,5 +1,5 @@
 d = dict(a=1, b=2)
-x = d.items()
-y = d.iteritems()
-z = d.viewitems()
+x = list(d.items())
+y = iter(d.items())
+z = d.items()

So

d.items() --> list(d.items())
d.iteritems() --> iter(d.items())
d.viewitems() --> d.items()

In short: items() and iteritems() were both dropped, and viewitems() was 
renamed items().
