Yes, lists are implemented as dynamic arrays (but you shouldn't care about  
it). "Textbook" linked lists are good for a CS course, but useless in most  
usual circumstances (think of memory fragmentation). There are AVL trees  
implemented in Python, but not built in.
Read the Python Tutorial specially this section

You may be interested in the collections module too
