If it is a path, the file will be opened and closed by ZipFile. mode: The mode can be either read 'r', write 'w', exclusive create 'x', or append 'a'. compression: ZIP_STORED (no compression), ZIP_DEFLATED (requires zlib), ZIP_BZIP2 (requires bz2) or ZIP_LZMA (requires lzma). allowZip64: if True ZipFile will create files with ZIP64 extensions when needed, otherwise it will raise an exception when this would be necessary. compresslevel: None (default for the given compression type) or an integer specifying the level to pass to the compressor. When using ZIP_STORED or ZIP_LZMA this keyword has no effect. When using ZIP_DEFLATED integers 0 through 9 are accepted. When using ZIP_BZIP2 integers 1 through 9 are accepted.

If pathname is a package directory, search the directory and all package subdirectories recursively for all *.py and enter the modules into the archive. If pathname is a plain directory, listdir *.py and enter all modules. Else, pathname must be a Python *.py file and the module will be put into the archive. Added modules are always module.pyc. This method will compile the module.py into module.pyc if necessary. If filterfunc(pathname) is given, it is called with every argument.

Consider a zip file with this structure:: . ├── a.txt └── b ├── c.txt └── d └── e.txt >>> data = io.BytesIO() >>> zf = ZipFile(data, 'w') >>> zf.writestr('a.txt', 'content of a') >>> zf.writestr('b/c.txt', 'content of c') >>> zf.writestr('b/d/e.txt', 'content of e') >>> zf.filename = 'mem/abcde.zip' Path accepts the zipfile object itself 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� c C s t �|�| _|| _dS )aX Construct a Path from a ZipFile or filename. Note: When the source is an existing ZipFile object, its type (__class__) will be mutated to a specialized type. If the caller wishes to retain the original type, the caller should either create a separate ZipFile object or pass a filename.
