Selecting the right data structure

Selecting the right data structure can have a profound impact on the performance of a program. If your program requires you to spend considerable time on lookups, use a dictionary, if feasible. When all that you need is to traverse over a collection, prefer lists over dictionaries because dictionaries take up more space. When your data is immutable, prefer tuples over lists because tuples can be traversed faster than lists.
