                                               SECTION B (Subjective Type Questions)

              A.  Short answer type questions:
                  1.  Differentiate between arithmetic operators and comparison operators.
                Ans.   Arithmetic Operators:  They are used to perform mathematical operations on variables and values. For example:

                    print(12+5); print(15-5); print(2*3)
                      Comparison Operators: These operators compare the values given on both sides of the operators and based on the
                    evaluation returns the Boolean value True or False. For example:
                    Num1<12, Num2>18, Num1==Num2
                  2.  What are sets in Python? Give an example.
                Ans.  Set is a mutable, unordered collection of values, of any type, with no duplicate element. For example:
                        >>> marks = {20,35,45,30,20,35}
                        >>> print(marks)
                          Output:
                          {35,20,45,30}
                  3.  Give rules for naming variables in Python.
                Ans.  The rules are as follows:
                       • An identifier can have letters in uppercase or lowercase, numbers or underscore(_).

                       • It cannot begin with a number or an underscore.
                       • No special characters like $, period(.), space, etc. are allowed.
