trying to run this code:

import urllib.request

req = urllib.request.Request('http://www.python.org')
with urllib.request.urlopen(req) as response:
the_page = response.read()
print(the_page)

will get me:

why am i doing this in drawbot?
trying to get my students to get data from public APIs to generate text/images and post to twitter.

i could:

install drawbot as a module?
roll my own version?

@justvanrossum ok so, no idea what has changed, but after i re-downloaded and reinstalled the same Py3 app. code runs fine now. screencap

@justvanrossum hmm ... the latest DrawbotPy3 version on the website is 3.113. just downloaded it again, to make sure (screenshot) though it does tell me i'm on 3.114 when i check for updates from within the app.

@justvanrossum actually, on 3.114 Python 2 code runs fine with the jpeg, I assumed it also had to do with not finding the image. apologies for the confusion.

@justvanrossum just tried the Python 2 (3.114) version with a different url and same problem.

code:

image('https://lumiere-a.akamaihd.net/v1/images/aliceinwonderland_-yes_celebrate_bc506b50.gif', (100,100))

output:
