Checking whether list element exists

[Rehceb Rotkiv]

I want to check whether, for example, the element myList[-3] exists. So 
far I did it like this:

index = -3
if len(myList) >= abs(index):
	print myList[index]

Another idea I had was to (ab-?)use the try...except structure:

index = -3
try:
	print myList[index]
except:
	print "Does not exist!"

Is it ok to use try...except for the test or is it bad coding style? Or 
is there another, more elegant method than these two?
