How to install and configure IPython so it uses Python3.2 on 11.10? I've checked that installing by

sudo apt-get install ipython

will uses python2.7.

[EDIT1]

$ sudo python3 configure.py

Julian Taylor has PPAs for IPython:

IPython stable (ppa:jtaylor/ipython)

IPython nightlies (ppa:jtaylor/ipython-dev)

For oneiric, installing ipython3 from either of those gets you the standard terminal IPython. The Qt console and the HTML notebook both work in Python 3, but you'll need to install some dependencies. There are instructions on the IPython wiki.

Following instructions at here, I get $ python3 configure.py python3: can't open file 'configure.py': [Errno 2] No such file or directory Where is this configure.py? –  Problemania Feb 1 '12 at 15:57
    
@user6076: When you do apt-get source python-qt4, it will create a directory python-qt4-..., which you need to cd into. I've updated the wiki to clarify this. –  Thomas K Feb 1 '12 at 18:27
    
Still not working because of sip not found, see in the original post. –  Problemania Feb 2 '12 at 3:54
    
@user6076: Have you installed python3-sip-dev? It's possible you also need python-sip-dev, I haven't tried without it. –  Thomas K Feb 2 '12 at 19:25
