Re: [Tutor] Ipython Queries
Thank you All. I forgot to update you guys , i use ubuntu 14.10 . I believe/was under assumption that we cannot used ipython both for python 2.x and python 3.x. So ipython is for python 2.x and ipython3 is for python 3.x Thanks, santosh On Sun, Mar 15, 2015 at 3:47 AM, Oscar Benjamin wrote: > On 14 March 2015 at 09:53, Steven D'Aprano wrote: > > On Fri, Mar 13, 2015 at 10:39:50PM +0530, Santosh Kumar wrote: > >> Hi All, > >> > >> I have installed both python2 and python3 in my system .

When you install ipython (or any Python package) you install it for a particular Python version. You haven't said how you installed either of the Python versions or ipython or which version of Python you installed ipython for. Assuming that you have installed ipython for Python 3 then you may be able to run ipython for Python 3 by typing one of the following in a terminal: $ ipython3 $ python3 -m IPython $ py -3 -m IPython (Note carefully that the I and P at the start of IPython in the last two examples are capitalised - the first example is all lower case). You may find that ipython is in the "programs" menu on Windows. I'm not really sure how that stuff works on newer versions of Windows though. Without knowing more about your setup it's hard to be specific about what you should do. What OS are you using (e.g. Windows 8?)? How did you install Python 2 and Python 3 and which versions (e.g. 2.7 and 3.4?). How did you install ipython? Which version of Python did you install it for? Do you know what folder the Python installations are in (e.g. C:\Python34)?

How/what is the easy way to > swith between python2 and python3 ? I don't think there is an easy way on Windows, but I could be wrong. You could try asking on a dedicated iPython mailing list. If you get an answer, please come back and tell us here so we can learn too. On Linux, install the ipython3 package. On Debian or Ubuntu systems, try: sudo aptitude install ipython3 and then run ipython3 instead of ipython. On Centos or Fedora systems: sudo yum install ipython3 will probably work if your system isn't too old. Or, you could try the instructions shown here: http://stackoverflow.com/questions/9386048/ipython-reads-wrong-python-version but I would be surprised if it works. (I just tried it, and it failed. You need to install all the ipython libraries into Python 3.) -- Steve ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
