Why can't I download a whole image file with urllib2.urlopen()
- by John Gann
When I run the following code, it only seems to be downloading the first little bit of the file and then exiting. Occassionally, I will get a 10054 error, but usually it just exits without getting the whole file. My internet connection is crappy wireless, and I often get broken downloads on larger files in firefox, but my browser has no problem getting a 200k image file. I'm new to python, and programming in general, so I'm wondering what nuance I'm missing.
import urllib2
xkcdpic=urllib2.urlopen("http://imgs.xkcd.com/comics/literally.png")
xkcdpicfile=open("C:\\Documents and Settings\\John Gann\\Desktop\\xkcd.png","w")
while 1:
chunk=xkcdpic.read(4028)
if chunk:
print chunk
xkcdpicfile.write(chunk)
else:
break
