This helped me out today with some backup scripts. Posting here so I can remember it. Idea and snippet adapted from: http://mail.python.org/pipermail/python-list/2007-February/596539.html
#!/usr/bin/env python
import os
import zipfile
def main():
zipper('c:/test', 'c:/temp/test.zip')
def zipper(dir, zip_file):
zip = zipfile.ZipFile(zip_file, 'w', compression=zipfile.ZIP_DEFLATED)
root_len = len(os.path.abspath(dir))
for root, dirs, files in os.walk(dir):
archive_root = os.path.abspath(root)[root_len:]
for f in files:
fullpath = os.path.join(root, f)
archive_name = os.path.join(archive_root, f)
print f
zip.write(fullpath, archive_name, zipfile.ZIP_DEFLATED)
zip.close()
return zip_file
if __name__ == '__main__':
main()
* code updated. there was a bug in the original I posted (cmg - 07/13/09)

hi corey, thanks for sharing this code. i extended zipper to have commandline options so it can be used for general recursive zipping. hope it helps. it's up on www.casualengineer.blogspot.com with credit given to you for inspiration
cheers

archive_name = os.path.basename(f)
zip.write( f, archive_name, zipfile.ZIP_DEFLATED)
print f
os.path.walk(dir, walker, z)

Hi,
Maybe I was doing something wrong - but your code didn't work for me.
It wouldn't handle sub-directories below the path.
Here is some code that seems to work for me (well I just created it now :) ).
Two other things I changed...
a) Used the more modern os.walk rather os.path.walk
b) removed the os.path.basename(f) call - this always gave you back what you had before the os.path.join on the previous line.
import os
import zipfile
def main():
zipper('tsearch', 'c:/_temp/testzip.zip')
def zipper(dir, zip_file):
zip = zipfile.ZipFile(zip_file, 'w', compression=zipfile.ZIP_DEFLATED)
# get the length of the root dir
root_len = len(os.path.abspath(dir))
for root, dirs, files in os.walk(dir):
# get the directories below the root
archive_root = os.path.abspath(root)[root_len:]
for f in files:
# full path to the file
fullpath = os.path.join(root, f)
# archive path to the file
archive_name = os.path.join(archive_root, f)
print f
zip.write(fullpath, archive_name, zipfile.ZIP_DEFLATED)
zip.close()
return zip_file
if __name__ == '__main__':
main()
(strange that you can't make Blogger treat that as Monospaced!
Mark, I just updated my code with the fix!
thanks,

Rayjan,
very cool :) thanks for the additions. see my updated post with some fixed code.
Hi Corey,
Thanks for sharing the code. It is now the backbone of a small auto backup script.
Zip file is being created but is empty for me. code below
#!/usr/bin/env python
import os, zipfile
def zipper(dir, zip_file):
z = zipfile.ZipFile(zip_file, 'w', compression=zipfile.ZIP_DEFLATED)
def walker(zip, dir, files, root=dir):
root_len = len(os.path.abspath(dir))
for root, dirs, files in os.walk(dir):
archive_root = os.path.abspath(root)[root_len:]
for f in files:
f = os.path.join(dir, f)
archive_name = os.path.basename(f)
zip.write( f, archive_name, zipfile.ZIP_DEFLATED)
print f
os.path.walk(dir, walker, z)
z.close()
return zip_file
if '__main__' == __name__:
# Late import, in case this project becomes a library, never to be run as main again
import optparse
# Populate our options, -h/--help is already there for you
usage = "usage: %prog [options]"
version="%prog 1.0"
parser = optparse.OptionParser(usage=usage, version=version)
parser.add_option("-d", "--dir", dest="inputDir", default="c:/test", action="store", help="sets the input directory to something other than the default (c:/test)")
parser.add_option("-f", "--file", dest="outputFile", default="c:/temp/test.zip", action="store", help="sets the output zip file to something other than the default (c:/temp/test.zip)")
parser.set_defaults()
# Parse the arguments (defaults to parsing sys.argv)
(options, args) = parser.parse_args()
# Here would be a good place to check what came in on the command line and
# call parser.error("Useful message") to exit if all is not well
if len(args) > 0 and (1 != options.inputDir or 1 != options.outputFile):
parser.error("Additional arguments are not supported\nYou can only change the inputDir or outputFile using the -d and -f options.\nType zippy.py -h for help.\n")
# Do the actual work
zipper(options.inputDir, options.outputFile)
