You shouldn't be worried a repeating few characters from a short,
simple print statement. It's not a mortal sin.
You don't need any ternary operator to avoid repetition, anyways. You
could factor the common parts out like this:
if n == 1:
what = "a car"
else:
what = "%d cars" % n
print "I saw %s" % what
but what's the point? It's just a few repeated characters two lines
apart. Peter's version is the most easily read version here,
including the one using the official ternary operator.
