zipfile

I'm working on a reporting application for my Django powered website. I want to run several reports and have each report generate a .csv file in memory that can be downloaded in batch as a .zip. I would like to do this without storing any files to disk. So far, to generate a single .csv file, I am following the common operation: mem_file = StringIO.StringIO() writer = csv.writer(mem_file) writer.writerow(["My content", my_value]) mem_file.seek(0) response = HttpResponse(mem_file, content_type='text/csv') response['Content-Disposition'] = 'attachment; filename=my_file.csv' This works fine, but

I've been learning python for about 3 weeks now, and I'm currently trying to write a little script for sorting files (about 10.000) by keywords and date appearing in the filename. Files before a given date should be added to an archive. The sorting works fine, but not the archiving It creates an archive - the name is fine - but in the archive is the complete path to the files. If i open it, it looks like: folder1 -> folder2 -> folder3 -> files . How can I change it such that the archive only contains the files and not the whole structure? Below is a snippet with my zip function, node is the

I have two zip files, both of them open well with Windows Explorer and 7-zip. However when i open them with Python's zipfile module [ zipfile.ZipFile("filex.zip") ], one of them gets opened but the other one gives error " BadZipfile: File is not a zip file ". I've made sure that the latter one is a valid Zip File by opening it with 7-Zip and looking at its properties (says 7Zip.ZIP). When I open the file with a text editor, the first two characters are "PK", showing that it is indeed a zip file. I'm using Python 2.5 and really don't have any clue how to go about for this. I've tried it both

I've been trying to use the zipfile and shutil.make_archive modules to recursively create a zip file of a directory. Both modules work great--except empty directories do not get added to the archive. Empty directories containing other empty directories are also silently skipped. I can use 7Zip to create an archive of the same path and empty directories are preserved. Therefore I know this is possible within the file format itself. I just don't know how to do it within Python. Any ideas? Thanks! There is a example using zipfile: import os, zipfile from os.path import join def zipfolder

I'm trying to extract user-submitted zip and tar files to a directory. The documentation for zipfile's extractall method (similarly with tarfile's extractall ) states that it's possible for paths to be absolute or contain .. paths that go outside the destination path. Instead, I could use extract myself, like this: some_path = '/destination/path' some_zip = '/some/file.zip' zipf = zipfile.ZipFile(some_zip, mode='r') for subfile in zipf.namelist(): zipf.extract(subfile, some_path) Is this safe? Is it possible for a file in the archive to wind up outside of some_path in this case? If so, what
