Q 2 - What is output for following code −

y = [4, 5,1j]
y.sort()

Answer : D

Explanation

we cannot compare complex numbers with numbers, so the output results in type error stating that complex numbers cannot be compared with <,>,=.

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 - Suppose we have two sets A & B, then A<B is:

A - True if len(A) is less than len(B).

B - True if A is a proper subset of B.

C - True if the elements in A when compared are less than the elements in B.

D - True if A is a proper superset of B.

Answer : B

Explanation

If A is proper subset of B then hen all elements of A are in B but B contains at least one element that is not in B.

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)

A - z is 100

new value of global z is: 100

value of z is 100

B - z is 100

new value of global z is: 100

value of z is 50

C - z is 100

new value of global z is: 50

value of z is 100

D - 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 - What is the output of the following code?

eval(''1 + 3 * 2'')

Answer : D

C - Infile = open.file(''c:\\scores.txt'',''r'')

D - Infile = open(''c:\\scores.txt'', ''r'')

Answer : D

You need to define the format in which you want to open the file. Proper path has to be declared by the user for the interpreter to reach the destination of the file.

Q 9 - Suppose you are using a grid manager then which option is best suitable to place a component in multiple rows and columns?
