In this task, the job is to create a new empty file called "output.txt" of size 0 bytes
and an empty directory called "docs". This should be done twice: once "here", i.e. in the current working directory and once in the filesystem root.

import os
for directory in ['/', './']:
  open(directory + 'output.txt', 'w').close()  # create /output.txt, then ./output.txt
  os.mkdir(directory + 'docs')                 # create directory /docs, then ./docs
