Q 1 - What is the output for −

S = [['him', 'sell'], [90, 28, 43]]

S[0][1][1]

Answer : A

Explanation

List can contain other list values.

So, in this question S[0] gives ['him', 'sell'], S[0][1] gives ‘sell' and S[0][1][1] gives ‘e'.

Remember, the index in python starts with ‘0'.

Q 2 - What is output for −

b = [11,13,15,17,19,21]

ptint(b[::2])

Answer : C

Explanation

b[::2] :- it iterates over the list with ‘2' increments

Q 3 - For tuples and list which is correct?

A - List and tuples both are mutable.

B - List is mutable whereas tuples are immutable.

C - List and tuples both are immutable.

D - List is immutable whereas tuples are mutable.

Answer : B

Explanation

list are mutable whereas tuples are immutable i.e. in list changes can be made but in tuples it is not possible, they can only be operated its value cannot be changed.

Q 4 - What is output of following code −

def func(n):
   if(n==1):
      return 1;
   else:
      return(n+func(n-1))
print(func(4))

Answer : B

Q 5 - What is output of following code −

l = [1,2,6,5,7,8]
l.insert(9)

A - l=[9,1,2,6,5,7,8]

B - l=[1,2,6,5,9.7,8] (insert randomly at any position)

C - l=[1,2,6,5,7,8,9]

D - Type Error

Answer : D

Explanation

listname.insert(x,y) method is used to insert a item at certain position in a list. x defines position at which the element will be added and y defines the element to be added in the list. And insert function takes exactly two arguments else it results in type error.

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 - Suppose we are given with two sets(s1&s2) then what is the output of the code −
