You can also make your own function to get the items as namedtuples.
That can work now with any class that defines items the current way.
from collections import namedtuple
Item = namedtuple('Item', ['key', 'value'])
def nameditems(d):
return (Item(*t) for t in d.items())
d = {'a': 1, 'b': 2}
for item in nameditems(d):
print(item.key, item.value)
Comparing that with Steve's example above though I don't see the
advantage of namedtuples here.
