11. What's the value of this Python expression: (2**2) == 4?

  • 4
  • 2**2
  • True
  • False

12. Complete the script by filling in the missing parts. The function receives a name, then returns a greeting based on whether or not that name is "Taylor".
def greeting(name):
if ___ == "Taylor":
return "Welcome back Taylor!"
___:
return "Hello there, " + name

print(greeting("Taylor"))
print(greeting("John"))

  • def greeting(name):
         if name == “Taylor”:
              return “Welcome back Taylor!”
         else: return “Hello there, “ + name

    print    (greeting(“Taylor”))
    print(greeting(“John”))

13. What’s the output of this code if number equals 10?
if number > 11:
print(0)
elif number != 10:
print(1)
elif number >= 20 or number < 12:
print(2)
else:
print(3)

  • 3

14. Is "A dog" smaller or larger than "A mouse"? Is 9999+8888 smaller or larger than 100*100? Replace the plus sign in the following code to let Python check it for you and then answer.
print("A dog" + "A mouse")
print(9999+8888 + 100*100)

  • “A dog” is larger than “A mouse” and 9999+8888 is larger than 100*100
  • “A dog” is smaller than “A mouse” and 9999+8888 is larger than 100*100
  • “A dog” is larger than “A mouse” and 9999+8888 is smaller than 100*100
  • “A dog” is smaller than “A mouse” and 9999+8888 is smaller than 100*100

15. If a filesystem has a block size of 4096 bytes, this means that a file comprised of only one byte will still use 4096 bytes of storage. A file made up of 4097 bytes will use 4096*2=8192 bytes of storage. Knowing this, can you fill in the gaps in the calculate_storage function below, which calculates the total number of bytes needed to store a file of a given size?
def calculate_storage(filesize):
block_size = 4096
# Use floor division to calculate how many blocks are fully occupied
full_blocks = ___
# Use the modulo operator to check whether there's any remainder
partial_block_remainder = ___
# Depending on whether there's a remainder or not, return
# the total number of bytes required to allocate enough blocks
# to store your data.
if partial_block_remainder > 0:
return ___
return ___

print(calculate_storage(1)) # Should be 4096
print(calculate_storage(4096)) # Should be 4096
print(calculate_storage(4097)) # Should be 8192
print(calculate_storage(6000)) # Should be 8192

  • def calculate_storage(filesize):
    block_size = 4096
    # Use floor division to calculate how many blocks are fully occupied
    full_blocks = filesize // block_size
    # Use the modulo operator to check whether there’s any remainder
    partial_block_remainder = filesize % block_size
    # Depending on whether there’s a remainder or not, return
    # the total number of bytes required to allocate enough blocks
    # to store your data.
    if partial_block_remainder > 0:
    return (full_blocks + 1) * block_size
    return full_blocks * block_size

    print(calculate_storage(1)) # Should be 4096
    print(calculate_storage(4096)) # Should be 4096
    print(calculate_storage(4097)) # Should be 8192
    print(calculate_storage(6000)) # Should be 8192
