But the expression result isn't even used. So this is better written:
matplotlib.pyplot.xlabel sets x-axis scaling, with no documented return
value.

If, as seems reasonable to assume, it returns None, the value of the
expression is 'None if x else None', which is to say, None.
Hardly matters what the return value is, given that the code ignores it.
I was not clear enough. To me, a 'conditional expression' that has an
unconditional value is a bit confusing. So I think the conditional
side-effect would be better written the way you did regardless of the
use or not of the value. If the unconditional value were not ignored, I
think it would be better used by itself.
