Every node is a file

And because in unix a directory is a folder, a node might also be a directory.

>>> from plant import Node
>>>
>>> functional_test_file = Node("tests/functional/test_fs.py")
>>> functional_test_file.is_dir
False
>>> functional_test_file.is_file
True
>>> functional_test_file.parent
Node('tests/functional')
>>> functional_test_file.parent.parent
Node('tests')
>>> functional_test_file.dir
Node('tests/functional')

Handy way to get to a directory from a file

.dir is a safe way to be in the current working directory

>>> from plant import Node
>>>
>>> unit_test_file = Node("tests/unit/test_base.py")
>>> unit_test_file.dir
Node('tests/unit')
>>> unit_test_file.dir.dir
Node('tests/unit')
>>> unit_test_file.dir.dir.dir
Node('tests/unit')
