                   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:

                 if (Test Expressions_1):

                     Indented block 1

                 elif (Test Expression_2):

                     Indented block 2
                 elif (Test Expression_3):

                     Indented block 3
                 else:
                     Indented block
