You could use enumerate() to number the items (careful it starts with 0):

   attributes = ['foo', 'bar']
   attributeNames = {}
   for n, attribute in enumerate(attributes):
       attributeNames["AttributeName.%d" % (n+1)] = attribute


Then use a generator expression to feed the dict:

   attributes = ['foo', 'bar']
   attributeNames = dict(("AttributeName.%d" % (n+1), attribute)
                         for n, attribute in enumerate(attributes))

Hope this helps,
