1 Consider the following code. What is the output of divide(2,4)?

def divide(a, b):

z = -1

try:

z = a / b

except ZeroDivisionError:

print('Can not divide by zero')

finally:

print('Result is', z)

 a Cannot divide by zero. Result is -1

 b Result is 0.5

 c Result is 2

 d Cannot divide by zero. Result is 2

2 Programmers can force their programs to throw an exception by using the _________ statement.

3 If no exception handler exists for an error type, then a(n) _______ may occur.

 a larch outbreak

 b bad grade

 c infinite loop

 d unhandled exception

4 The _________ keyword binds a name to the exception being handled.

 a larch

 b list

 c equals

 5 What kind of exception will the following code snippet throw?

>>> add(3,'hello')

 a NameError

 b AttributeError

 c IOError

 d NumberTypeError

6 What is the output of the following code snippet?

class B(Exception):

pass

class C(B):

pass

class D(C):

pass

for cls in [B, C, D]:

try:

raise cls()

except D:

print("D")

except C:

print("C")

z = x/y

 a A Larch

 b A ValueError

 c A ZeroDivisionError

 d A DivideByZeroError

8 Consider the following code. What is the output of divide(0,1)?

def divide(a, b):

z = -1

try:

z = a / b

except ZeroDivisionError:

print('Can not divide by zero')

finally:

print('Result is', z)

 a Cannot divide by zero. Result is -1

 b Result is 0.0

 c Result is 0

 d Cannot divide by zero. Result is 0

9 An AttributeError occurs if a function does not exist in an imported module. Fill in the missing code to handle AttributeErrors gracefully and generate an error if other types of exceptions occur.

import my_lib 

try: 

result = my_lib.larch()

____________:

print('No larch() function in my_lib.')

 a larch AttributeError

 b except AttributeError

 c AttributeError

 d except

10 If a programmer chooses not to use a built-in exception type, then she may use a ___________

exception type.

 a larch

 b custom

 c finally

 d default
