NUMBER
                 Integer numbers, floating-point numbers and complex numbers are the built-in numeric data
                 types of Python.

                 Integer/Long

                 Integers are whole numbers consisting of + or – signs. They do not have decimal places between
                 them. For example, 87, -3 are called integer numbers.

                 Float
                 Float data type represents numbers that contain a decimal point. For example, 0.6, -3.257 are
                 called floating-point numbers. These numbers can also be written using ‘e’ or ‘E’ to represent the
                 power 10.


                 SEQUENCE

                 A sequence is an ordered collection of items of similar or different data types. The three types of
                 sequence data types are Strings, Lists and Tuples.

                 Strings
                 A string is a sequence of one or more characters put in single quotes, double quotes or triple quotes
                 which is used to represent text-based information. The quotes are not a part of the string. For
                 example, "hello","Orange Education", 'Amit', '365'.


                 List
                 A list is a collection of data elements separated by comma (,) and enclosed within square

                 brackets []. We can also create a list with the elements that are the same or have different data
                 types. For example, [1,2,5], ['HELLO',45,87.6].

                 Tuple
                 A tuple is just like a list. It contains a group of elements that can be of different data types. The
                 elements in the tuple are separated by commas (,) and enclosed in parentheses (). The difference
                 between a list and a tuple is that list can be modified but tuples cannot be modified after it is
                 created. For example, (7, 9.5, 3), ('a',4,3).


                 BOOLEAN
                 Boolean is a data type with two built-in values: True or False. They are used in logical evaluation.
                 A True statement returns value 1 while a False statement returns value 0.


                 TYPE CONVERSION IN PYTHON
                 Type conversion in Python refers to changing the data type of a variable from one type to
                 another. It can be classified into two types:

                   Implicit Type Conversion: Python automatically converts one data type to another when
                   there is no risk of data loss. This process is known as implicit type conversion or automatic
                   type casting.



                                                                                    Tokens and Data Types in Python  91
