python - IPython 和 bpython 中的 Ctrl+D 等价物？

Question

在标准的 Python 交互式 shell 中，我可以按 Ctrl+D 关闭标准输入并显示输出:

$ 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)

>>> 

但在 IPython 和 bpython 中，Ctrl+D 不起作用，我必须按 Enter 两次才能得到结果:

IPython:

In [1]: for f in range(5):
   ...:     print f     (I press Enter here)
   ...:                 (I press Enter here)
   ...:                 (I press Enter here)

python:

>>> for f in range(5):
...     print f     (I press Enter here)
...                 (I press Enter here)

我通过将 IPython 升级到版本 0.12-r1 解决了一半问题:

[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}
     Installed versions:  0.12-r1(11:47:58 AM 03/16/2012)(examples qt4 readline smp -doc -emacs -matplotlib -mongodb -notebook -sqlite -test -wxwidgets)

注意 ...: 你会看到我只需要按 Enter 两次:第一次换行，第二次一个关闭标准输入并显示结果:

$ ipython
Python 2.7.2 (default, Mar  7 2012, 21:18:58) 
Type "copyright", "credits" or "license" for more information.

关于bpython，它需要在显示输出之前转到没有缩进的行。出于测试目的，如果我使用两个嵌套的 for 循环，我必须按 Enter 四次:

>>> for i in range(2):
...     for j in range(2):
...         print i*j
...         
...     
...
