[Tutor] tripping up zip

[paul at entropia.co.uk]

Dear list,

I've been trying to make a quick backup script, but its failing to add some files to the 
archive. Any idea where I'm going wrong?
Works fine using nt4/Python 2.2.2 (#37, Oct 14 2002, 17:02:34) [MSC 32 bit (Intel)] on win32



## path module by http://www.jorendorff.com/articles/python/path/
## win xp pro Python 2.3.2 (#49, Oct  2 2003, 20:02:00) [MSC v.1200 32 bit (Intel)] on 
win32



from path import path
import zipfile

f = path('C:\Documents and Settings\XP Pro\My Documents\personal')
nuzip = zipfile.ZipFile('C:\ziptests\ziptest.zip','w')

## this is a document I added to test things and
## it appears in the final archive
## but fails in the for loop and is listed as doing so

x='C:\\Documents and Settings\\XP Pro\\My Documents\\personal\\INDIA TRAVEL 
ITENARY.doc'
nuzip.write(x,x,zipfile.ZIP_DEFLATED)
files = 0
folders = 0
failed =''
failures= 0
bax = f.walkdirs()
for topfiles in f:
    if topfiles.isfile():
#        print topfiles
        files = files + 1
        try:
            nuzip.write(topfiles,topfiles,zipfile.ZIP_DEFLATED)
        except:
            failed=failed+topfiles.name + ' \n'
            failures = failures + 1
  
## this will sweep the sub directories if I ever get it working
      
##for folder in bax:
###   folders = folders + 1
###   for filer in folder:
##        if filer.isfile():
##            #print filer
##            files = files + 1
##            #try:
##                #nuzip.write(filer,filer,zipfile.ZIP_DEFLATED)
##            #except:
##                #failed=failed+filer.name + ' \n'
##                #failures = failures + 1



nuzip.printdir()
nuzip.close()
print 'there are %d folders and %d files with %d failures' %(folders, files, failures)
print 'The following failed: '
print failed
