Python 3 dict question

[dmitrey]

hi all,
suppose I have Python dict myDict and I know it's not empty.
I have to get any (key, value) pair from the dict (no matter which
one) and perform some operation.
In Python 2 I used mere
key, val = myDict.items()[0]
but in Python 3 myDict.items() return iterator.
Of course, I could use
for key, val in myDict.items():
   do_something
   break
but maybe there is any better way?

Thank you in advance, D.
