Just because `os.path` is accessible through just `import os`, doesn't mean that you shouldn't import it explicitly. As the Zen of Python says, explicit is better than implicit. After all it's documented separately at https://docs.python.org/3/library/os.path.html

If you see `os.path.basename` what could `os.path` be? It would be a module most of the time because it's written with lowercase. `itertools.chain.from_iterable` [1] would be a notable exception.
