Well, how is the output directory different ? Is it just a timestamp
like 'YYYYMMDD' that obviously changes every day or is it named after
the file used ? If it is timestamp style you can do
import zipfile, os, sys, time
folder_name = time.strftime("%Y%m%d", time.localtime(time.time()))
event_zip = ("C:\\Temp\\data4event.zip")
z = zipfile.ZipFile(event_zip, 'r')
zList = z.namelist()
for zItem in zList:
print "Unpacking",zItem
zRead = z.read(zItem)
z1File = open(os.path.join(folder_name, zItem),'wb')
z1File.write(zRead)
z1File.close
print "Finished"
That will create a folder in your current working directory with the
name of todays date and unzip it there. This is just one example
route.
