(Note that assignment is not an expression in Python; assigment is a
statement.)

I would say the latter is more Pythonic, because it:
* Better conveys the intention (“set the value of the ‘self.key’
attribute”).
* Uses the built-in mechanisms of Python (don't invoke magic attributes,
instead use the system that makes use of them behind the scenes).
* Expresses that intention more concisely (fewer terms).
* Expresses that intention more clearly (less syntactic noise).
