Code Sample, a copy-pastable example if possible

Running on the REPL with Python 2.7:

Problem description

The Series.items method is mysteriously absent on Python 2.7, though Series.iteritems works fine on both legacy and modern Python.

Expected Output

Series.items should iterate over (index, value) tuples.

Output of pd.show_versions()

This was fixed (recently) in #17214 and will be in the next release.
