Disregarding some ugly hacks, Python does not permit assignment in
expressions, so what you're asking for is not possible.
For the goods of readability, prevention of errors, and simplicity,
Python forces you to do it the "long way" (the Right Way(tm) if you
ask most Python partisans).

If you could explain your situation and the context of your question
in greater detail, someone might be able to suggest an alternate
structure for your code which obviates your desire for such a
construct.

Cheers,
Chris
