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.

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 = '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('abcde.zip', 'a.txt') >>> b Path('abcde.zip', 'b/') name property: >>> b.name 'b' join with divide operator: >>> c = b / 'c.txt' >>> c Path('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: >>> str(c) 'abcde.zip/b/c.txt' z>{self.__class__.__name__}({self.root.filename!r}, {self.at!r})r� c C s t �|�| _|| _d S r� )r r r� �at)r� r� r r r r r� s z Path.__init__c C s t �| jj| j�S r� )� functools�partialr� rA r r� r r r rA s z Path.openc C s t �| j�d��S �Nrv )r r� r r� r� r r r r! s z Path.namec O s6 | � � �$}tj|f|�|��� W 5 Q R � S Q R X d S r� )rA r3 � TextIOWrapperr> )r� �args�kwargs�strmr r r � read_text s zPath.read_textc C s( | � � �}|�� W 5 Q R � S Q R X d S r� r� )r� r$ r r r � read_bytes s zPath.read_bytesc C s t �|j�d��| j�d�kS r )r r� r r� )r� r� r r r � _is_child" s zPath._is_childc C s t | j|�S r� )r r� )r� r r r r �_next% s z Path._nextc C s | j p| j �d�S r )r �endswithr� r r r r� ( s z Path.is_dirc C s | � � S r� )r� r� r r r �is_file+ s z Path.is_filec C s | j | j�� kS r� )r r� r r� r r r r� . s z Path.existsc C s. | � � std��t| j| j�� �}t| j|�S )NzCan't listdir a file)r� r| r� r( r� r� �filterr' )r� Zsubsr r r �iterdir1 s z Path.iterdirc C s t �| jj| j�S r� )r r2 r� rB r r� r r r �__str__7 s z Path.__str__c C s | j j| d�S )Nr� )� _Path__reprr r� r r r r� : s z Path.__repr__c C s t �| j|�}| �| j�|��S r� )r r2 r r( r� r )r� �add�nextr r r �joinpath= s z Path.joinpathc C s( t �| j�d��}|r |d7 }| �|�S r )r r� r r� r( )r� Z parent_atr r r �parentC s z Path.parentN)r� )r r r r r. r� r] rA r! r% r& r' r( r� r* r� r, r- r� r1 � __truediv__r2 r r r r r � s* @ c s� dd l }d}|j|d�}|jdd�}|jdddd d � |jd d d ddd� |jdddddd� |jddddd � |�| �} | jd k r�| j}t|d��}|�� }W 5 Q R X |r�td� |�� td� n�| j d k r�| j }t|d��}|� � W 5 Q R X n�| j d k �r,| j \}}t|d��}|� |� W 5 Q R X n�| jd k �r�| j�d�} | j} � fd d �� t| d ��\}| D ]P} tj�| �} | �s�tj�tj�| ��} | d tjtjfk�r�d } � || | � �qfW 5 Q R X d S ) Nr z3A simple command-line interface for zipfile module.)� descriptionT)Zrequiredz-lz--list� <zipfile>zShow listing of a zipfile)�metavar�helpz-ez --extractr )r5 z <output_dir>z Extract zipfile into target dir)�nargsr6 r7 z-cz--create�+)z<name>z<file>zCreate zipfile from sourcesz-tz--testzTest if a zipfile is validr^ z.The following enclosed file is corrupted: {!r}z Done testingc sp t j�|�r | �||t� nPt j�|�rl|r8| �||� tt �|��D ]$}� | t j�||�t j�||�� qFd S r� ) ry r� r� r r r� r� r� r2 )rV r� �zippathZnm��addToZipr r r< s s �zmain.<locals>.addToZipr_ r� )�argparse�ArgumentParserZ add_mutually_exclusive_group� add_argument� parse_argsZtestr r� r| r r^ r� r� r� Zcreate�popry r� r� r� r� r� ) r" r= r4 �parser�groupr� rV Zbadfiler� Zzip_name�filesr� r: r r; r �mainK s\ � � � � rE �__main__)N)N)�r Zbinasciir �importlib.utilr� r3 r ry r r� r� rF r} ro r� r r� r� � ImportErrorr� r� �__all__� Exceptionr r r r r� r� r� r r r r r r� r� r� r� r] r\ r� r[ rL rM rN rO rP rQ rR ra r} r~ r� r� r� r� Z_CD_CREATE_VERSIONZ_CD_CREATE_SYSTEMZ_CD_EXTRACT_VERSIONZ_CD_EXTRACT_SYSTEMZ _CD_FLAG_BITSZ_CD_COMPRESS_TYPEZ_CD_TIMEZ_CD_DATEZ_CD_CRCZ_CD_COMPRESSED_SIZEZ_CD_UNCOMPRESSED_SIZEr� r� r� Z_CD_DISK_NUMBER_STARTZ _CD_INTERNAL_FILE_ATTRIBUTESZ _CD_EXTERNAL_FILE_ATTRIBUTESr� r� r� r� r� Z_FH_EXTRACT_VERSIONZ_FH_EXTRACT_SYSTEMr� Z_FH_COMPRESSION_METHODZ_FH_LAST_MOD_TIMEZ_FH_LAST_MOD_DATEZ_FH_CRCZ_FH_COMPRESSED_SIZEZ_FH_UNCOMPRESSED_SIZEr� r� rG rH rE rJ rK rI Z_CD64_SIGNATUREZ_CD64_DIRECTORY_RECSIZEZ_CD64_CREATE_VERSIONZ_CD64_EXTRACT_VERSIONZ_CD64_DISK_NUMBERZ_CD64_DISK_NUMBER_STARTZ _CD64_NUMBER_ENTRIES_THIS_DISKZ_CD64_NUMBER_ENTRIES_TOTALZ_CD64_DIRECTORY_SIZEZ_CD64_OFFSET_START_CENTDIRrY ZStructr. r8 r= r rX r9 �objectr r� r� r� r� r� r� r� r� r� r r r4 r rN r r r r �dict�fromkeysr r r r r rE r r r r r �<module> sl � += q& � & AN /2 =
