download a zip file to a local drive and extract all files to a destination folder using python 2.5

Question

I am trying to download a zip file to a local drive and extract all files to a destination folder.

so i have come up with solution but it is only to \"download\" a f

Answer 1

urllib.urlretrieve can get a file (zip or otherwise;-) from a URL to a given path.

extractall is indeed new in 2.6, but in 2.5 you can use an explicit loop (get all names, open each name, etc). Do you need example code?

So here's the general idea (needs more try/except if you want to give a nice error message in each and every case which could go wrong, of which, of course, there are a million variants -- I'm only using a couple of such cases as examples...):

import os
import urllib
import zipfile

def getunzipped(theurl, thedir):
  name = os.path.join(thedir, 'temp.zip')
  try:
    name, hdrs = urllib.urlretrieve(theurl, name)
  except IOError, e:
    print "Can't retrieve %r to %r: %s" % (theurl, thedir, e)
    return
  try:
    z = zipfile.ZipFile(name)
  except zipfile.error, e:
    print "Bad zipfile (from %r): %s" % (theurl, e)
    return
  for n in z.namelist():
    dest = os.path.join(thedir, n)
    destdir = os.path.dirname(dest)
    if not os.path.isdir(destdir):
      os.makedirs(destdir)
    data = z.read(n)
    f = open(dest, 'w')
    f.write(data)
    f.close()
  z.close()
  os.unlink(name)

Answer 2

The shortest way i've found so far, is to use +alex answer, but with ZipFile.extractall() instead of the loop:

from zipfile import ZipFile
from urllib import urlretrieve
from tempfile import mktemp

filename = mktemp('.zip')
destDir = mktemp()
theurl = 'http://www.example.com/file.zip'
name, hdrs = urlretrieve(theurl, filename)
thefile=ZipFile(filename)
thefile.extractall(destDir)
thefile.close()

Answer 3

For downloading, look at urllib:

import urllib
webFile = urllib.urlopen(url)

For unzipping, use zipfile. See also this example.
