                  You will get the following output:





















                  THE if-elif-else STATEMENT

                  Sometimes, we need to evaluate multiple statements to get a certain result. In such scenarios, we
                  can use the if-elif-else statements to evaluate multiple scenarios. First, it checks and evaluates
                  the  first  condition.  If it  is  true,  it  will
                  execute the respective statement(s), but             Test       True
                  if the condition is false, it goes to the elif    expression           Statement 1
                                                                        1
                  statement     and     evaluated      those              False
                  conditions.  Finally, if none of the

                  conditions evaluates to true it executes             Test       True
                  the  else block.  The syntax  of the              expression           Statement 2
                                                                        2
                  if-elif-else statement is as follows:
                                                                          False
                      if (conditional expression):

                              statement(s)                             Test       True
                                                                    expression           Statement 3
                      elif (conditional expression):                    3

                              statement(s)                                False

                      elif (conditional expression):
                                                                                         Body of else
                              statement(s)
                      else:                                                                              Statement just
                              statement(s)                                                               below if-elseif
