It is comprised of a set of characters that can also contain spaces and numbers. Strings . String values. To make this precise, a universal computer (or universal Turing machine) must be specified, so that "program" means a program for this universal machine. The latter may allow its elements to be mutated and the length changed, or it may be fixed (after creation). S The following code example creates an empty Dictionary of strings with string keys and uses the Add method to add some elements. In other words, a variable in a python program gives data to the computer for processing. In example 7 the strings are concatenated using the addition operator '+'.
