Python 2.7 cant decode deflate encoding

Question

For some reason urllib is corrupting documents that i download from a website. The url is definitely correct. The documents download with their correct names but they appear corrupted once opened. I found that the download is encoded with deflate so i attempted to decode it but i keep getting either these two errors when i modify the "zlib" part.

errors:

error-2 while preparing to decompress data: inconsistent stream state

or

error -3 while decompressing data: incorrect header check

here is a code snippet of where the problem is:

def download_file(url, name):
try:
f = urllib.urlopen(url)
fh = open(name, 'wb')
if f.info().get('content-encoding') == 'deflate':
 fh = zlib.decompress(f.read(),16 +zlib.MAX_WBITS)
#fh.write(f.read())
fh.close()
print "  File Downloaded : " , name

except Exception:
    raise
