That is not the Pythonic way. "# Do something with i" might also raise
an IndexError and they you are screwed. The Pythonic way is something
like:
try:
i = somelist.index(thing)
except IndexError:
print "Oh noes!"
else:
# Do the thing with i
And for many cases this actually is worse/less readable than the
alternative would have been if list.index() returned -1.
