Relational Operators


                  We  have  studied  about  the  arithmetic  operators;  another  category  is  the  relational
                  operators. Relational operators are used to compare the values of the operands and return

                  the result as true or false.  Python provides the following relational operators:

                   Operator       Name       Description                                   (x=8 and y=6)     Output
                                                                                              Example
           Prime (Ver. 2.2)-VII  ==  Not equal It checks if the values of two                   x == y       FALSE                                                                                                                                      MORE ON PYTHON
                                             It checks if the values of two
                                   Equal
                                             operands are equal or not. If yes, then
                                             the condition becomes true.
                                                                                                x != y
                        !=
                                                                                                             TRUE
                                             operands are equal or not. If the
                                             values are not equal, then the condition
                                             becomes true.

                                             becomes true.
                        <       Less than It checks if the value of left operand                x < y        FALSE
                                             is less than the value of right operand.
                                             If yes, then the condition becomes
                                             true.
                       >=        Greater  It checks if the value of left operand                x >= y       TRUE
                                 than or     is greater than or equal to the value
                                 equal to    of right operand. If yes, then the
                                             condition becomes true.
                       <=       Less than  It checks if the value of left operand               x <= y       FALSE
                                 or equal  is less than or equal to the value
                                    to       of right operand. If yes, then the
                                             condition becomes true.

                  Let us use them in a program:
