[Python] Variable variables?

[Rob Hudson]

Every now and then I hit a need for what's called "variable variables" 
in the PHP world.  Here's what usually happens:

Let's say I have 3 lists: list1, list2, list3

And I want to write a loop to do something to each list.  I want to do 
something like this:

	for i in range(3):
		myloop = "loop" + str(i)
		# Do something to myloop, but myloop the interpretted
		# variable, not myloop the string

1) Can python do this?

2) Is there a better way to handle this same idea another way?

Thanks,
Rob
