Q1. What does the following Python3 code do? (using python 3.X version): n = int (input ('Enter a number?'))
i = 1
while i <= n:
i = i+1
print (i)
1.Print all integers from 1 to n
2.Print all integers from 1 to n-1
3.Print all integers from 2 to n
4.Print all integers from 2 to n+1
Reason: option 4 will be correct because if we run this program we will get correct answer as per the 2 to n+1 or we can say option 4.

Q2. 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)
1.13
2.10
3.6
4.9
Reason: As per the above commands or program we will get 10 or option 2 as the correct answer.

Q3. 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))
1.8
2.102
3.9
36
72
72
4.Error
Reason: As per the above commands or programs, we will get the option 3 or 9 36 72 72 as the correct answer.

Q4. 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 X for the code to work correctly? (using python 3.X version): N = int (input ('Enter N:'))
i = 1
while ( i < N ) :
if ( X ):
print(i)
i = i + 1
1.i//2 == 0
2.i%2! = 0
3.i//2! = 0
4.i%2 == 0
Reason: if we replace X with i%2=0 we will get the desired output, so here option 4 is the correct answer.

Q5. 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 X for the code to work correctly? (using python 3.X version): N = int(input('Enter N:'))
i = 1
while ( i < N ) :
print(i)
X
1.i%2 == 1
2.i = i + 2
3.i = 1 + i * 2
4.i = i * 2
Reason: if we replace X with i=i+2 then we will get the desired output, so here option 2 is the correct answer.
