Sure you don't need this to be 'wb' instead of 'w'?
'wb' does the trick. Thanks all!
Here is the final working code, i used an index(i)
to see how many reads took place, i have to assume there is
a default buffer size:
import urllib2
a = open('adobe.pdf', 'wb')
i = 0
for line in
urllib2.urlopen('http://www.whirlpoolwaterheaters.com/downloads/6510413.pdf'):
i = i + 1
a.write(line)
print "Number of reads: %d" % i
a.close()
NEW QUESTION if y'all are still reading:
Is there an integer increment operation in Python? I tried
using i++ but had to revert to 'i = i + 1'
for line in urllib2.urlopen(url):
a.write(line)
I also don't know if this "for line...a.write(line)" loop is doing
newline translation. If it's a binary file, you should use .read()
(perhaps with a modest-sized block-size, writing it in a loop if the
file can end up being large.)
