Q 1 - What is the output for −

'you are doing well' [2:999]

A - 'you are doing well'

B - ' '

C - Index error.

D - 'u are doing well'

Answer : D

Slicing will never give us an error even if we give it too large of an index for the string. It will just return the widest matching slice it can.

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 - In the following options which are python libraries which are used for data analysis and scientific computations

Answer : D

Numpy,Scipy,pandas are few libraries in python which are used for data analysis and scientific computations.

Q 4 - What is output for −

2 * 2 **3

Answer : C

Explanation

2**3 gives 2*2*2 i.e. 8, then 2*8 gives 16, since order of precedence is ** then*. ** implies raise to power''.

Q 5 - What command is used to shuffle a list L'?

A - L.shuffle()

B - random.shufflelist(L)

C - shuffle(L)

D - random.Shuffle(L)

Answer : D

Explanation

To shuffle the list we use random.shuffle(List_name) function.

Q 6 - What is the output of the code?

try: 
   list = 5*[0]+5*[10] 
   x = list[9] 
   print(''Done!'') 
except IndexError: 
   print(''Index out of Bond! '') 
else: 
   print(''Nothing is wrong!'') 
finally: 
   print(''Finally block!'')

A - Finally Block!'

B - Done!' follow by Nothing is wrong!'

C - Nothing is wrong!' followed by Finally block!'

D - Done!' follow by Nothing is wrong!' followed by Finally block'.

Answer : D

Explanation

In the above Try block we make a list of total 10 elements by adding 5 times zero and 5 times 10. Thus when we try to find out the element at index 9 no error is raised by Python.

Q 7 - Discuss the outcome of the code?

def func1(n): 
   if(n==0): 
      return 0 
   else: 
      return(n+func1(n-1)) 
def func2(n, result): 
   if(n==0): 
      return(result) 
   else: 
      return(func2(n-1, n+result))  
print(func1(4)) 
print(func2(4,0))

A - Func1 is tail recursion.

B - Func1 and Func2 are tail recursions.

C - Func2 is only tail recursion.

D - Neither Func2 nor Func1 is tail recursion.

Answer : B

Explanation

A function call is said to be tail recursive if there is nothing to do after the function returns except return its value.
