The simplest form.
The in operator takes precedence over the or operator, so there is no need for parentheses around x in a_dictionary or around y in a_dictionary.
On the other hand, you do need parentheses around x or y here, for the same reason — in takes precedence over or. (Note: this code is completely different from the previous line. Python interprets x or y first, which results in either x (if x is true in a boolean context) or y. Then it takes that singular value and checks whether it is a key in a_dictionary.)
-The in operator takes precedence over the + operator, so this form technically doesn’t need parentheses around x + y, but 2to3 includes them anyway.
-This form definitely needs parentheses around y in a_dictionary, since the in operator takes precedence over the + operator.
