      Arguments:
          path (str): A path to split.
  
      Returns:
          (str, str): A tuple containing the path and the extension.
  
      Example:
          >>> splitext('baz.txt')
          ('baz', '.txt')
          >>> splitext('foo/bar/baz.txt')
          ('foo/bar/baz', '.txt')
          >>> splitext('foo/bar/.foo')
          ('foo/bar/.foo', '')
