 Using one `getInventoryList` is usually much more efficient than doing multiple `getInventory`/`getInventoryAssetPrice` calls. 
 For example, this code:
 ```python
-print "N1's inventory of R1 is {inventory}, value is {value}".format(
-        inventory=getInventory(node_uid=N1.getUid(), resource=R1.getUid(),
-        asset_price=getInventoryAssetPrice(node_uid=N1.getUid(), resource=R1.getUid()))
-print "N2's inventory of R1 is {inventory}, value is {value}".format(
-        inventory=getInventory(node_uid=N2.getUid(), resource=R1.getUid(),
-        asset_price=getInventoryAssetPrice(node_uid=N2.getUid(), resource=R1.getUid()))
+print "Alice's has {inventory} candies, value is {value}".format(
+        inventory=getInventory(node_uid=alice.getUid(), resource=candy.getUid(),
+        asset_price=getInventoryAssetPrice(node_uid=alice.getUid(), resource_uid=candy.getUid()))
+print "Bob's has {inventory} candies, value is {value}".format(
+        inventory=getInventory(node_uid=bob.getUid(), resource=candy.getUid(),
+        asset_price=getInventoryAssetPrice(node_uid=bob.getUid(), resource_uid=candy.getUid()))
 ```
 
 can be written more efficiently with `getInventoryList` this way:
 
 ```python
-for brain in getInventoryList(node_uid=(N1.getUid(), N2.getUid()),
-                              resource_uid=R1.getUid(),
+for brain in getInventoryList(node_uid=(alice.getUid(), bob.getUid()),
+                              resource_uid=candy.getUid(),
                               group_by_node=True):
-    print "{node}'s inventory of R1 is {inventory}, value is {value}".format(
+    print "{node}'s inventory of candy is {inventory}, value is {value}".format(
         node=brain.node_title,
         inventory=brain.total_inventory,
         asset_price=brain.total_price)
