well, that's odd, it certainly works for me:
Python 2.3.4 (#1, Feb 2 2005, 12:11:53)
Type "copyright", "credits" or "license" for more information.
IPython 0.6.16.svn -- An enhanced Interactive Python.
? -> Introduction to IPython's features.
%magic -> Information about IPython's 'magic' % functions.
help -> Python's own help system.
object? -> Details about 'object'. ?object also works, ?? prints more.
In : 4/3
Note that I'm running from SVN, but I doubt that has anything to do with this
issue. All I did was put in my ipythonrc file the line I mentioned:
execute exec __IP.compile('from __future__ import
division','<input>','single') in __IP.shell.user_ns
I can confirm (I triple-checked) that commenting this out gives me 4/3->1,
while keeping it in produces the result above. Perhaps there's a subtle
difference between python 2.3.3 and 2.3.4 on this matter, but that also sounds
At any rate, if the solution you posted (-q new) works for you, that's great.
I just wanted to clarify that this one does work at least on my system,
though I'm at a loss to guess why it fails for you.
