Revision

1.       Write answers to the questions based on the following program:

i. a = int(input(“Enter a number:”))

if (a>0):

print(“positive”)

elif (a<0):

print(“negative”)

else:

print(“zero”)

 

a.What is the objective of the given program?

The program checks whether the entered number is positive, negative, or zero and displays the result.

b. Does the program give any error if int() function is removed from the program? Give reason.

Yes, it will give an error. Without int(), the input is taken as a string, and Python cannot compare a string with a number using > or <, which causes a TypeError.

 

ii. Write answers to the questions based on the following program:

n = int(input("Enter a number:"))
if (n % 2 == 0):
    print("Even Number")
else:
    print("Odd Number")

a. What is the purpose of the given program?

The program checks whether the entered number is even or odd.
b. What will happen if the user enters 7 as input?

Since 7 % 2 ≠ 0, the output will be:
Odd Number

 

x = int(input("Enter a number:"))

if (x >= 50):

    print("Pass")

else:

    print("Fail")

a.       What does the program check?

The program checks whether the entered number is greater than or equal to 50 to determine pass or fail.
b. What will be the output if the user enters 45?

Since 45 < 50, the output will be:Fail

2.       Write the output of the following program using a dry run table:

for i in range(2,21,2):

print(i)
