tself or a filename

    >>> root = Path(zf)

    From there, several path operations are available.

    Directory iteration (including the zip file itself):

    >>> a, b = root.iterdir()
    >>> a
    Path('mem/abcde.zip', 'a.txt')
    >>> b
    Path('mem/abcde.zip', 'b/')

    name property:

    >>> b.name
    'b'

    join with divide operator:

    >>> c = b / 'c.txt'
    >>> c
    Path('mem/abcde.zip', 'b/c.txt')
    >>> c.name
    'c.txt'

    Read text:

    >>> c.read_text()
    'content of c'

    existence:

    >>> c.exists()
    True
    >>> (b / 'missing.txt').exists()
    False

    Coercion to string:

    >>> import os
    >>> str(c).replace(os.sep, posixpath.sep)
    'mem/abcde.zip/b/c.txt'

    At the root, ``name``, ``filename``, and ``parent``
    resolve to the zipfile. Note these attributes are not
    valid and will raise a ``ValueError`` if the zipfile
    has no filename.

    >>> root.name
    'abcde.zip'
    >>> str(root.filename).replace(os.sep, posixpath.sep)
    'mem/abcde.zip'
    >>> str(root.parent)
    'mem'
    z>{self.__class__.__name__}({self.root.filename!r}, {self.at!r})r†
