[2]  What does the following Python3 code do? (using python 3.X version)

n = int(input(‘Enter a number?’))
i = 1
while i < n:
print (i)
i = i+1
(a): Print all integers from 1 to n
(b): Print all integers from 1 to n-1
(c): Print all integers from 2 to n
(d): Print all integers from 2 to n-1
Answer: (b) Print all integers from 1 to n-1

[3] What does the following Python3 code do? (using python 3.X version)

n = int(input(‘Enter a number?’))
i = n
while i > 0 :
print (i);
i = i-1

(a): Print all integers from n to 1
(b): Print all integers from 1 to n
(c): Print all integers from n-1 to 1
(d): Print all integers from n-1 to 0
Answer: (a) Print all integers from n to 1

[4]  What will the output of the following Python3 program (using python 3.X version)?

n = 13
sum = 0
while (n > 1):
n = n//2
sum = sum + n
print(sum)

(a): 13
(b): 10
(c): 6
(d): 9
Answer: (b) 10

[5]  What will the output of the following Python3 program? If the program has error, select the option ERROR (using python 3.X version)

n,p = 9,1
while (n >= 1):
n,p = n//2,n*p
print(int(p))

(a): 8
(b): 102
(c): 9, 36, 72, 72
(d): Error
Answer:(c)  9, 36, 72, 72

[6]  The following code should print all positive even numbers less than or equal to N. N is         taken as input from the user. What should replace the ???? for the code to work                 correctly?(using python 3.X version)

       N = int(input(‘Enter N:’))

       i = 1

      while ( i < N ) : 

      if ( ???? ):

        print(i)

      i = i + 1

(a): i//2 == 0
(b): i%2 != 0
(c): i//2 != 0
(d): i%2 == 0
Answer: (d) i%2 == 0

[7]  The following code is supposed to read 5 inputs from the user and print the last input. It does not produce the desired answer. Why? (Select the choice that corresponds to the error having the simplest fix for the code.)(using python 3.X version)

inp = 5
while (inp > 0):
last = input(‘next num? ‘)
inp = inp + 1
print (last)

(a): The code works correctly
(b): Bad initialization: While loop variable
(c): Bad Update: Variable
(d): Bad Termination: The termination condition should be: inp > 10
Answer:(b) Bad initialization: While loop variable

[8]  The following code should print all positive odd numbers less than or equal to N. N is taken as input from the user. What should replace the ???? for the code to work correctly? (using python 3.X version)

N = int(input(‘Enter N:’))
i = 1
while ( i < N ) :
print(i)
????

(a): i%2 == 1
(b): i = i + 2
(c): i = 1 + i * 2
(d): i = i * 2
Answer:(b) i=i+2
