The parent_directory function returns the name of the directory that's located just above the current working directory. Remember that '..' is a relative path alias that means "go up to the parent directory". Fill in the gaps to complete this function.

import os
def parent_directory():

  # Create a relative path to the parent 
  # of the current working directory 
  relative_parent = os.path.join(os.getcwd(), os.pardir)
  # Return the absolute path of the parent directory
  return os.path.abspath(relative_parent)

print(parent_directory())
