Document Summary

The ith member of a finite sequence (x[i]) The slice of a finite sequence from the ith to the jth member of a finite sequence (x[i:j]) Strings: a finite sequence of characters, type str. Lists: a finite sequence of values, type list. Files: a finite sequence of data stored on a persistent data storage device. Allow the sharing of data between programs, users, computers, and storage devices. Programs can use files for both input and output. Alan turing~ww2~broke the code of the german enigma machine~ the turing award is the highest award you can receive in computing. Objects: a mutable, active value that combines data and operations and communicates via message passing. An objects data is a set of variables called fields. An object"s operations is a set of functions called methods, and determine the objects behaviour. An accessor is a method that that retrieves information about the state of an object.
