In the standard Python interactive shell, I can press Ctrl+D to 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+D doesn't work, I must press Enter twice to get the results:
IPython:

...: print f (I press Enter here)

I solved half the problem by upgrading IPython to version 0.12-r1:

Pay attention to the ...:
you'll see that I only need to press Enter two times: the first one to make a new line and the second one to close stdin and display the results:
$ ipython

About bpython, it needs to go to the line which has no indentation before showing the output. For testing purposes, if I use two nested for
loops, I must press Enter four times:
>>> for i in range(2):
... for j in range(2):
... print i*j
...
