Question

我有一些像这样的代码：

form IPython import embed
for item in my_item_list:
    embed()

如果我随后用

运行此程序

python my_example_program.py

在循环的第一次迭代中，我被放入一个ipython shell中，可以按照我的意愿检查item和环境。

在退出ipython时，循环恢复，然后我可以按照您的预期检查下一个item和环境。

有没有办法让我从ipython中退出这段代码（这样我就会返回shell提示符）。在任何方面都没有打开另一个shell并杀死进程？

IPython中有一个%kill_embedded命令它不会直接返回shell提示符，但会跳过其他嵌入实例。

from IPython import embed

for item in range(5):
    print 'embedding', item
    embed()

这是输出：

 $ python my_example_program.py
embedding 0

UPD（06.03.2016）：似乎%kill_embedded功能在IPython 4.0中有所破坏;您可以使用%exit_raise来引发异常并返回shell。

我可以从调用代码中退出ipython吗？
