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 - Name the error that doesn't cause program to stop/end, but the output is not the desired result or is incorrect.

Answer : C

Explanation

logical error doesn't cause the program to stop/end, but the output is not the desired result or is incorrect.

Q 5 - What is output of following −

print(''abbzxyzxzxabb''.count(abb',-10,-1))

Answer : B

Explanation

It Counts the number of times the substring abb' is present starting from position 2 and ending at position 11 in the given string.

Q 6 - Guess the output −

def main(): 
   try: 
      func() 
      print(''print this after function call'') 
   except ZeroDivisionError: 
      print('Divided By Zero! Not Possible! ') 
   except: 
      print('Its an Exception!') 
def func(): 
   print(1/0) 
main()

A - Its an Exception!'

B - Divided By Zero! Not possible!'

C - print this after function call' followed by Divided By Zero! Not Possible!'

D - print this after function call' followed by Its an Exception!'

Answer : B

Explanation

The function func' will not run because it contains an exception. So in try and expect block. The function called under try will not run and will move to except block which defines the type of exception present in the function func'. Thus block of statements present in except ZeroDivisionError is printed.

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 - Which code is used to open a file for binary writing?
