Program 6: To check if the given number is lucky or not, if the given number is greater than
             zero and is even, then print ‘Lucky number’ else print ‘Not a lucky number’
















            On running the above program, we get the following output:

              Write the logic in Word document to check if the input number is positive or negative. Write the program in
              Python for the logic created.

            The if…elif…else Ladder

            The if…elif…else ladder is another type of if statement. It helps us to test multiple conditions and
            follows a top-down approach. In this, as soon as the condition of the if evaluates to be true, the indented
            block associated with that ‘if’ is executed, and the rest of the ladder is avoided. If none of the conditions
            evaluates to true, then the final else statement gets executed.

            The syntax of if...elif...else ladder is shown below:

            Syntax:

            if (Test Expressions_1):

                Indented block 1

            elif (Test Expression_2):

                Indented block 2


                                                                               #Conditional Statements in Python 133
