Get first and second values in dictionary in CPython 3.6

Now that dictionaries are ordered in python 3.6, it must be the case that there is a way to get the first and second values of a dictionary in only two lines. Right now, I have to use 7 lines to accomplish this:

for key, value in class_sent.items():
    i += 1
    if i == 1:
        first_sent = value
    elif i == 2:
        second_sent = value

I also tried:

first_sent = next(iter(class_sent))
    second_sent = next(iter(class_sent))

But in that case the second_sent is equal to the first_sent. If anyone knows how to obtain the first and second values in a dictionary in as few lines as possible I would seriously appreciate it.
