    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’

                       Program6.py
                    File  Edit  Format   Run   Options   Window    Help

                    #Program to check lucky number
                    number = int(input('Enter a number: '))
                    if(number > 0):
                        if(number % 2 == 0):
                            print('Lucky number')
                        else:
                            print('Not a lucky number')
                    else:
                        print('Try again....')

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

                       Output

                    Enter a number: 21
                    Not a lucky number

                    Enter a number: 12
                    Lucky number

                      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 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:
