Is Ctrl + D equivalent in IPython and bpython?
In the standard Python interactive shell, I can press Ctrl+ Dto close stdin and it shows the output:
$ python
Python 2.7.2 (default, Mar 7 2012, 21:18:58)
[GCC 4.5.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> for f in range(5):
... print f (I press Enter here)
... (I press Ctrl+D here)

But in IPython and bpython Ctrl+ Ddoesn't work, I have to double click Enterto get the results:
IPython:
In [1]: for f in range(5):
...: print f (I press Enter here)
...: (I press Enter here)

I solved half of the problem by updating IPython to version 0.12-r1:
[I] dev-python/ipython
Available versions: 0.10 0.10.1 0.10.2 (~)0.12-r1 {doc emacs examples gnuplot matplotlib mongodb notebook qt4 readline (+)smp sqlite test wxwidgets}

About bpython, you need to jump to a line that is not indented before showing the output. For testing purposes, if I use two nested loops for
, I have to press Enterfour times:
>>> for i in range(2):
... for j in range(2):
... print i*j
