                                       Some More Programs




                  In the previous chapter, you have learned what is Python, its features, how to install Python,
                  programming in Python and variable.

                  In this chapter, you will learn about data types, comments, operators and its precedence.


                      DATA TYPES


                  Data types are used to define the type of value a data can contain. Each variable in Python is
                  associated with some data type. Each data type requires a different amount of memory and has
                  some specific operations performed on it.  Data types are divided into four categories as shown
                  below:


                                                              Data Types




                                    Numbers                   Sets              Sequence               Boolean





                      Integer/long                Float                String                  Lists




                                    Complex               Dictionary              Tuple
