And now for the "readable" list comprehension version:

    [x==0 and 1 or math.sin(x)/x for x in myList]

Now even though I'm into the short-circuiting of and-or and even
occasionally have used such masturbation techniques as this, I don't
think it qualifies as pythonic.

If it was me, I would probably even have written:

    [x and math.sin(x)/x or 1 for x in myList]
