>>> str(12)

                  ‘12’
              >>> int(True)

                  1
              >>> bool(0)
                  False
            You can get the data type of any object by using type( ) function. For example,

              >>> type(10)

              <class 'int'>
              >>> type("abc")
              <class 'str'>

              >>> type(14.5)
              <class 'float'>

            Literals
            It is defined as any data stored in a variable. This data can be String literals are enclosed in single or double
            quotes. For example,

                       "Hello"
                       ‘Python’
               • Numeric literals: They can be integer, float or complex. For example,

                       14
                       20.5
                       2+5j
               • Boolean literals: They can be True or False. For example,

                       True
               • Special literals: Only None is a special literal. It means something not yet created.

            Punctuators

            Punctuators are special symbols used in Python to organise statements and expressions. Most commonly used
            punctuators in Python are:

            ‘ " # \ () {} [] @ , : . =


            Operators
            Operators are special symbols used to perform mathematical, logical and relational operations on variables
            and values. The variables or values on which the operators work are called operands. Some commonly used
            operators in Python are arithmetic operators, relational operators, logical operators and augmented assignment
            operators.


            Arithmetic Operators
            Arithmetic operators are used to perform mathematical operations on variables and values.
