They have to be stored somewhere. If items are deleted, the order of the remaining items is retained. A chain of ifs is an O(n).

If we explain the difference by Big O concepts, dictionaries have constant time complexity, O(1) while lists have linear time complexity, O(n). 1 # retrieve the value for a particular key 2 value = d[key] Thus, Python mappings must be able to, given a particular key object, determine which (if any) value object is associated .
