      1- 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”.

      Answer-

      def greeting(name):
        if name == "Taylor":
          return "Welcome back Taylor!"
        else:
          return "Hello there, " + name
      
      print(greeting("Taylor"))
      print(greeting("John"))

      2- What’s the output of this code if number equals 10?

      Answer-

      if number > 11: 
        print(0)
      elif number != 10:
        print(1)
      elif number >= 20 or number < 12:
        print(2)
      else:
        print(3)

      3- 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.

      Answer- `print(“A dog” > “A mouse”)
      print(9999+8888 > 100*100)`

      4- 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?

      Answer-

      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 = block_size%filesize
          # 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 8192
          else:
              return 4096
              #pass
              
          return full_blocks
      
      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
