items() returns a list, iteritems() returns an iterator. If you don't
actually need an explicit list, iteritems() saves the cost of creating
it.
Having said that, Kent I am not 100 percent sure of what you menat when you
mention a two-level dict. Can you give me a very brief example?
Your dict d would look like this:
d={
1: {23A:[a,b,c,d], 24A:[b,c,d]},
2: {23A:[a,b], 24A:[a,b,c,d]}
}
Lads...
>>> d={
... 1: {23A:[a,b,c,d], 24A:[b,c,d]},
... 2: {23A:[a,b], 24A:[a,b,c,d]}
... }
File "", line 2
1: {23A:[a,b,c,d], 24A:[b,c,d]},

Let's get a proper syntax for our data before attempting to process it.

When you say that the User class should have a UserProfile as an
attribute, would it look something like this?
from lastfmapi import UserProfile
class User (object):
def __init__:
self.UserProfile = UserProfile('Bob')
Yes, that's about right. Of course 'Bob' should be an argument passed
to __init__()
Also what do you mean by 'accessors' for Neighbors ?
class User(object):
...
def getNeighbors():
""" Returns a list of this user's neighbors """
and similar for getTopArtists(), etc.
A couple of caveats though.
Don't forget "self", it should be :
class User (object):
def __init__(self):
self.UserProfile = UserProfile('Bob')
Passing 'Bob' to __init__ would be :
class User (object):
def __init__(self, User='Bob'):
self.UserProfile = UserProfile(User)

sorry I meant :
amtinput = int (input ("Enter an amount: "))
amounts[index] = amtinput
