On the Mac running Mavericks, I have successfully managed to install and use
the requests library for HTTP and HTTPS requests using Python 2. But I'd like
to move to Python 3.
I downloaded the most recent stable version of Python 3 for Mac. All is well. I
did a pip3 install requests command and it worked. I could then start the
interpreter and perform a simple HTTP GET request:
$ python3
Python 3.4.2 (v3.4.2:ab2c023a9432, Oct 5 2014, 20:42:22)
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import requests
>>> r = requests.get("http://www.google.com";)
>>> r
<Response [200]>
So, with that success, I created an executable script filled with the same
commands:
#!/usr/bin/env python3
import requests
r = requests.get("http://www.google.com";)
print(r)
At first it failed because it couldn't find httplib2. Not sure why, but I
installed httplib2 and now get the following error:
$ ./test.py
Traceback (most recent call last):

AttributeError: 'module' object has no attribute '__all__'
Here is the full list of installed packages that I have in python3 (the list in
python2 is huge and not posted here):
$ pip3 list
httplib2 (0.9)
pip (1.5.6)
requests (2.5.1)
setuptools (2.1)
urllib3 (1.10)
Notre that if I change python3 to python in my script, it works fine using the
default Python 2.7.5 version. And as a Plan B I can stay with Python 2.7.5. But
I'd really like to move to Python 3 on the Mac.
Thanks in advance for any thoughts or help!
