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.
