    Answer the following Question

                                                                             (4 marks)

1.Write a Program to find a number is divisible by 4 or not

num=int(input("enter a number .."))

if num %4==0:

    print(num, "is divisible  by 4.")

else:

   print(num, "is not divisible  by  4")

2.Find the greatest of three number using Nested if

a=20

b=30

c=15

if a>b:

       if a>c:

              res=a

       else:

              res=c

elif b>c:

       res=b

else:

       res=c

print(“Greatest value=”,res)

3.Write a Program to check the given number is Positive or Negative or Zero

num=float(input("enter a number: "))

if num >=0:

   if num ==0:

       print("zero")

else:

   print("positive number")

else:

   print("negative number")

4.Write a program to print days of week in numbers(1 .. 7) using  if..elif..else

dofweek=int(input(“Enter a day of week between 1…7?”))

if  dofweek>=1 and dofweek<=7

if dofweek== 1 : print(“Sunday”)

if dofweek== 2 : print(“Monday”)

if dofweek== 3 : print(“Tuesday”)

if dofweek== 4 : print(“Wednesday”)

if dofweek== 5 : print(“Thursday”)

if dofweek== 6 : print(“Friday”)

if dofweek== 7 : print(“Saturday”)

5.Write a program to print 1 to 100  odd number using for loop

Answer:

for val in range(1,10,2):

    print(val)

Output:

>>>

1

3

5

7

9

6.Write a program to print for loop with else

digits=[1,2,3,4,5,6,7,8,9,10]

for i digits:

    print(i)

else:

print("no items left.")

7.write a program to print sum of the digit using while loop

n=int(input("enter n:"))

sum=0

i=1

while i<=n:

  sum= sum +i

  i = i+1

  print("the sum is",sum)

8.Write a program for break,continue and pass

Break

for val in "string":

    if val == "i":

        break

    print(val)

print("The end")

 

Continue

for val in "string":

   if val == "i":

        continue

    print(val)

print("the end")

Pass

sequence ={'p','a','s','s'}

for val in sequence:

    pass
