pylib7zip is a direct binding to 7z.dll from the 7-zip project (7zip.org)
7z.dll uses Windows COM+ calling conventions without registering itself with the COM server and has an over-engineered slightly pathological OOP API.
Currently only works on Windows with Python 3.3.
This provides roughly the same functionality as lib7zip does for C++ and SevenZipSharp does for C# but with a clean Pythonic API.
Like lib7zip getting metadata and extracting files are the only operations supported, creating archives, or updating them in-place is not supported.
This is beta software and may crash if used in an unusual (or even a usual) way.
- 7z.so/7z.dll from http://7zip.org or p7zip on *Nix
- CFFI
- enum34
By default the path to 7z.dll/7z.so will be autodetected.

from lib7zip import Archive, formats

for format in formats:
print(format.name, ', '.join(format.extensions))
#type of archive will be autodetected
#pass in optional forceformat argument to force the use a particular format (use the name)
#pass in optional password argument to open encrypted archives.
with Archive('path_to.7z') as archive:
#extract all items to the directory, directory will be created if it doesn't exist
archive.extract('extract_here')
#list all items in the archive and get their metadata
for item in archive:
print( item.isdir, item.path, item.crc)
#extract a particular archive item
# like extract, accepts a password argument, useful if different
# items in the archive have different passwords
archive[0].extract('extract to here.txt')
#extract a particular archive item to a python stream object
stream = io.BytesIO()
archive[0].extract(stream)
stream.getvalue() # a bytes object containing the contents of item 0This code is licensed under the BSD 2-clause license.
