IMPORTANT 

(PYQ)

1. Find the output :

def ChangeVal(M, N):

    for i in range(N):

        if M[i] % 5 == 0:

            M[i] //= 5

        if M[i] % 3 == 0:

            M[i] //= 3

ChangeVal(L, 4)

for i in L:

    print(i, end='#')

2.What will be the output of the following code?

def Call(P=40, Q=20):

    P = P + Q

    Q = P - Q

    print(P, '@', Q)

    return P

3.What will be the output of the following code?

import random

for i in range(Begin, End):

    print(Colours[i], end="&")

4.What will be the output of the following code?

def Update(X=10):

X += 15

print('X = ', X)

Update()

print('X = ', X)

5.What will be the output of the following code?

def Change(X):

  global G

  N=len(X)

  for i in range(N):

      X[i] += G

      

Change(L)

for i in L:

  print(i,end='$')

   print(a[i],end='#')

(A) W#         (B) W#i#

(C) W#s#     (D) W#i#s#

8.The code provided below is intended to swap the first and last elements of a given tuple. However, there are syntax and logical errors in the code.

Rewrite it after removing all errors. Underline all the corrections made

def swap_first_last(tup)

    if len(tup) < 2:

        return tup

    new_tup = (tup[-1],) + tup[1:-1] + (tup[0])

return new_tup

result = swap_first_last((1, 2, 3, 4))

print("Swapped tuple:", result)

9.Rao has written a code to input a number and check whether it is prime or not. His code is having errors. Rewrite the correct code and underline the corrections made.

def prime():

n=int(input("Enter number to check :: ")

for i in range (2, n//2):

if n%i=0:

print("Number is not prime \n")

break

else:

print("Number is prime \n’)

10. What will be the output of the following code?

def Diff(N1,N2):

  if N1>N2:

      return N1-N2

  else:

      return N2-N1

 

NUM= [10,23,14,54,32]

for CNT in range (4,0,-1):

 A=NUM[CNT]

 B=NUM[CNT-1]

 print(Diff(A,B),'#', end=' ')
