Q 3 - For tuples and list which is correct?
A - List and tuples both are mutable.
B - List is mutable whereas tuples are immutable.

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 - Suppose we have a set a = {10,9,8,7}, and we execute a.remove(14) what will happen ?
A - We cannot remove an element from set.
Answer : C
Explanation
since there is no such element in the set, so key error is raised.
Q 5 - What is the output of the code?
def f():
global z
print('z is: ', z)
z=50
print('new value of global z is: ', z)
f()
print('Value of z is: ', z)
new value of global z is: 100
value of z is 100
new value of global z is: 100
value of z is 50
new value of global z is: 50
value of z is 100
new value of global z is: 50
value of z is 50
Answer : D
Explanation
Here in the above code ‘global’ keyword is used to state that ‘z’ is global variable. So when we assign a value to z in the function then the new assigned value is reflected whenever we use the value of ‘z’ in the main block or outside the function.
Q 6 - Analyze the given below code?
class Demo:
def __init__(self,d):
self.d=d
def print(self):
print(d)
a = Demo(''Hello'')
a.print()
A - You cannot use print(self) as a function name.
B - Program has an error because class A does not have a constructor.
C - Program will print ‘Hello’ if we change print(d) to print(self.d).
Answer : C
Explanation
D stores the argument value here. Thus when we call the class ‘‘Hello’’ is passed as an argument which is stored in the variable d.
Answer : D
Explanation
we need to define the set by including the keyword ‘set’.
