zipfile.ZipFile解压文件

class ZipFile(builtins.object)

 |  Class with methods to open, read, write, close, list zip files.

 |  

 |  z = ZipFile(file, mode="r", compression=ZIP_STORED, allowZip64=True)

 |  

 |  file: Either the path to the file, or a file-like object.

 |        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.

 |  

 |  Methods defined here:

 |  

 |  __del__(self)

 |      Call the "close()" method in case the user forgot.

 |  

 |  __enter__(self)

 |  

 |  __exit__(self, type, value, traceback)

 |  

 |  __init__(self, file, mode='r', compression=0, allowZip64=True)

 |      Open the ZIP file with mode read 'r', write 'w', exclusive create 'x',

 |      or append 'a'.

 |  

 |  __repr__(self)

 |      Return repr(self).

 |  

 |  close(self)

 |      Close the file, and for mode 'w', 'x' and 'a' write the ending

 |      records.

 |  

 |  extract(self, member, path=None, pwd=None)

 |      Extract a member from the archive to the current working directory,

 |      using its full name. Its file information is extracted as accurately

 |      as possible. `member' may be a filename or a ZipInfo object. You can

 |      specify a different directory using `path'.

 |  

 |  extractall(self, path=None, members=None, pwd=None)

 |      Extract all members from the archive to the current working

 |      directory. `path' specifies a different directory to extract to.

 |      `members' is optional and must be a subset of the list returned

 |      by namelist().

 |  

 |  getinfo(self, name)

 |      Return the instance of ZipInfo given 'name'.

 |  

 |  infolist(self)

 |      Return a list of class ZipInfo instances for files in the

 |      archive.

 |  

 |  namelist(self)

 |      Return a list of file names in the archive.

 |  

 |  open(self, name, mode='r', pwd=None, *, force_zip64=False)

 |      Return file-like object for 'name'.

 |      

 |      name is a string for the file name within the ZIP file, or a ZipInfo

 |      object.

 |      

 |      mode should be 'r' to read a file already in the ZIP file, or 'w' to

 |      write to a file newly added to the archive.

 |      

 |      pwd is the password to decrypt files (only used for reading).

 |      

 |      When writing, if the file size is not known in advance but may exceed

 |      2 GiB, pass force_zip64 to use the ZIP64 format, which can handle large

 |      files.  If the size is known in advance, it is best to pass a ZipInfo

 |      instance for name, with zinfo.file_size set.

 |  

 |  printdir(self, file=None)

 |      Print a table of contents for the zip file.

 |  

 |  read(self, name, pwd=None)

 |      Return file bytes (as a string) for name.

 |  

 |  setpassword(self, pwd)

 |      Set default password for encrypted files.

 |  

 |  testzip(self)

 |      Read all the files and check the CRC.

 |  

 |  write(self, filename, arcname=None, compress_type=None)

 |      Put the bytes from filename into the archive under the name

 |      arcname.

 |  

 |  writestr(self, zinfo_or_arcname, data, compress_type=None)

 |      Write a file into the archive.  The contents is 'data', which

 |      may be either a 'str' or a 'bytes' instance; if it is a 'str',

 |      it is encoded as UTF-8 first.

 |      'zinfo_or_arcname' is either a ZipInfo instance or

 |      the name of the file in the archive.
