Q 1 - What is output for −

'search'. find('S') ?

A - s

B - -1

C -

D - None of the above

Answer : B

Explanation

The method find() is case sensitive.

Q 2 - What is the output of following code −

[ (a,b) for a in range(3) for b in range(a) ]

A - [ (1,0),(2,1),(3,2)]

B - [ (0,0),(1,1),(2,2)]

C - [(1,0),(2,1),(2,1)]

D - [ (1,0),(2,0),(2,1)]

Answer : D

Explanation

This is nested for loop. The output of first for loop will be the value for the next loop.

Q 3 - Select the option for following code −

s = 0
for d in range(0, 5, 0.1):
 s += d
 print(s)

Answer : D

Explanation

we will get type error during runtime as float object cannot be interpreted as integer. Here 0.1 is the float value.

Q 4 - What is output of following code −

def func(x, ans):
   if(x==0):
      return 0
   else: 
      return func(x-1, x+ans) 
print(func(2,0))

Answer : A

Q 5 - Find the output of the code?

def f(a, b = 1, c = 2):
   print('a is: ',a, 'b is: ', b, 'c is: ', c)
f(2, c = 2)
f(c = 100, a = 110)

A - a is: 2 b is: 1 c is: 2

a is: 110 b is: 1 c is: 100

B - a is: 2 b is: 2 c is: 2

a is: 110 b is: 2 c is: 100

C - a is: 0 b is: 2 c is: 2

a is: 110 b is: 0 c is: 100

D - a is: 110 b is: 0 c is: 100

a is: 110 b is: 0 c is: 100

Answer : A

Explanation

Value of Arguments is passed to the parameters in order of their sequence.

Q 6 - What is the output of the following code?

class P: 
   def __init__(self): 
      self.__x=100 
      self.y=200 
   def print(self): 
      print(self.__x, self.y)  
class C(P): 
   def __init__(self): 
      super().__init__() 
      self.__x=300 
      self.y=400  
d = C() 
d.print()

Answer : B

Explanation

In the above code x is a private variable declared in the class P. Thus value of x cannot be changed in the class C which inherits class P. But y is not a private variable thus its value can be changed.

Q 7 - What is the out of the code?

def rev_func(x,length): 
   print(x[length-1],end='' '') 
   rev_func(x,length-1) 
x=[11, 12, 13, 14, 15] 
rev_func(x,5)

A - The program runs fine without error.

B - Program displays 15 14 13 12 11.

C - Program displays 11 12 13 14 15.

D - Program displays 15 14 13 12 11 and then raises an index out of range exception.

Answer : D

Explanation

In the print statement of rev_func we use the index value of list x. We decrement the value of length of function because it becomes the index of x in the print statement.

Q 8 - Select the correct function among them which can be used to write the data to perform for a binary output?
