Python has a wealth of built-in data structures, and many applications are built from built-in data structures. These collections cover a variety of situations. The built-in tuple and string structures are different from list structures. There are some important similarities between them, but there are also some differences. These built-in data structures help us work with data collections. It is difficult to determine which data structure is suitable for a certain scenario....
