The oft-misquoted Python precept isn't "There's only one way to do it,"
it's more like, "There's (usually) only one _right_ way to do it." 
There is always more than one way to do something in any general,
powerful, expressive programming language, and Python is no exception.

The addition of a conditional operator to Python would resolve the issue
of which is the right way to do it (conditional evaluation within an
expression with short circuiting), so on the contrary, its addition
would not only be not un-Pythonic, but highly Pythonic.
