I disagree.

I disagree.

In the first example it is obvious to the reader that you're
checking to see if my_dictionary contains "orange" as a key.
In the second example it is not obvious whether the code is
checking whether my_dictionary contains "orange" as a key or as
a value.

I find the first version more obvious.
