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)

我使用的版本:

[I] dev-python/bpython

最佳答案
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}

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

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
...
