What is the output of the following snippet?

def fun (x):

    if x % 2 ==0:

         return  1

else:

          return 2

print (fun(fun(2)))

• The code will cause a runtime error

• 2

• None

• 1

How many stars (*) will the following snippet send to the console?

i = 0

while i < i + 2:

     i += 1

     print ("*")

else:

      print ("*")

• two

• one

• zero

• the snippet will enter an infinite loop, printing one star per line

What is the expected behavior of the following program?

try:

     print (5/0)

      break

except:

      print ("Sorry, something went wrong...")

except (ValueError, ZeroDivisionError):

      print ("Too bad...")

• The program will cause a ZeroDivisionError exception and output a default error message

• The program will cause a ValueError exception and output the following message: Too bad...

• The program will cause a SyntaxError exception

• The program will raise an exception handled by the first except block.

• The program will cause a ZeroDivisionError exception and output the following message: Too bad...

What is the output of the following piece of code?

print ("a", "b", "c", sep="sep")

• abc

• asepbsepcsep

• asepbsepc

• a b c

The following snippet:

def func (a, b):

     return b ** a

print (func(b=2, 2))

• will output None

• is erroneous

• will output 2

• will output 4

What is the output of the following code if the user enters a 0?

try:

     value = input("Enter a value: ")

     print (int(value)/len(value))

except ValueError:

     print ("Bad input...")

except ZeroDivisionError:

     print ("Very bad input...")

except TypeError:

     print("Very very bad input...")

except:

     print ("Booo!")

• Booo1

• Very bad input...

• Very very bad input...

• 1.0

• 0.0

How many hashes (#) will the following snippet send to the console?

lst = [[x for x in range (3)] for y in range (3)]

for r in range (3):

     for c in range (3):

          if lst [r][c] % 2 !=0:

               print ("#")

• six

• zero

• three

• nine

What is the output of the following piece of code if the user enters two lines containing 3 and 6 respectively?

y = input()

x = input ()

print (x+y)

• 6

• 36

• 63

• 3

Assuming that my_tuple is a correctly created tuple, the fact that tuples are immutable means that the following instruction:

my_tuple[1] = my_tuple[1] +my_tuple[0]

• is illegal

• can be executed if and only if the tuple contains at least two elements

• is fully correct

• may be illegal if the tuple contains strings

Which of the following snippets shows the correct way of handling multiple exceptions in a single except clause?

• except TypeError, ValueError, ZeroDivisionError

       # Some code

• except (TypeError, ValueError, ZeroDivisionError):

       # Some code

• except (TypeError, ValueError, ZeroDivisionError)

       #Some code

• except: (TypeError, ValueError, ZeroDivisionError)

       #Some code

• except TypeError, ValueError, ZeroDivisionError:

       # Some code
