Q1. Write a program to print the following pattern

5 5 5 5 5

4 4 4 4

3 3 3

2 2

1

Q2. Find errors in the following code:

a = int(“Enter any number”)

for i in Range[2,6]

    if a=i

      print(“A”)

    else

      print(“B”)

Q3. Write a program to accept decimal number

    and display its binary number.

Q4. Accept a number and check whether it is

    palindrome or not.

Q5. Write a program to accept a number and check whether it is a perfect number or not.

(Perfect number is a positive integer which is equal to the sum of its divisors like divisors of 6 are 1,2,3, and sum of divisors is also 6, so 6 is the perfect number)

Q6. Write a program to find the sum of the following series(accept values of x and n from user)

1 + x/1! + x2/2! + ……….xn/n!

Q7. Write a program to print the following pattern

A

B C

D E F

G H I J

K L M N O

Q8. Write a program to find the sum of following (Accept values of a, r, n from user)

a + ar + ar2 + ar3 + ………..arn

Q9. for x in range(10,20):

      if (x%2==0):

           continue

       print(x)

Q10. Write a function to display prime numbers below 25.

    and even numbers that fall between 12 and 37

    (including both numbers)

Q5. Write a program to display all the numbers 

    which are divisible by 11 but not by 2 between

    100 and 500.

Q6. How many times the following loop execute?

c = 0

while c < 20:

           c += 2

Q7. Write the output of the following.

c = -9

while c < 20:

               c += 3

               print(c)

 

Q8. Write a program to print first 20 natural

    numbers except multiple of 2 & 3.

 

Q9. Write a program to print table of a number

    (accepted from user) in the following format.

    Like : input number is 7, so expected output  

    is

    7 * 1 = 7

    7 * 2 = 14 and so on

 

Q10. Write a program that keep on accepting number

     from the user until user enters Zero.

Python : Looping Statement Test 4

Python : Looping Statement Test 4

Q1. What is the use of range function in python?

Q2. Name three jump statements in python and explain any one.

Q3. Write the output of the following program.

Code

Output

x = "123"

for i in x:

  print(i)

 

 

i=8

while True:

  if i%3==0:

    break

  print("A")

 

 

i=9

while True:

  if i%3==0:

    break

  print("A")

 

 

i=0

while i<3:

  print(i)

  i=i+1

else:

  print(0)

 

 

i=0

while i<3:

  print(i)

  i=i+1

print(0)

 

 

i=0

while i<3:

  print(i)

  i=i+1

  print(0)

 

 

i=2

for x in range(i):

  i+=1

  print(i)

  print(i)

 

 

i=2

for x in range(i):

  x+=1

  print(x)

print(x)

 

 

i=2

for x in range(i):

  x+=1

  print(x)

  print(x)

 

 

i=100

while i<57:

  print(i)

  i+=5

 

 

i=100

while i>57:

  print(i+1)

  i+=5

 

 

 

Q4. Write the output and convert it into for loop.

i=100

while i>57:

               print(i)

               i-=5

 

 

Solution of Q3.

Code

3

i=8

while True:

  if i%3==0:

    break

  print("A")

 

Infinite loop

i=9

while True:

  if i%3==0:

    break

  print("A")
