我有这样的代码:
form IPython import embed
for item in my_item_list:
embed()
如果我然后运行这个程序
python my_example_program.py
在循环的第一次迭代中,我进入了一个 ipython shell,并且可以检查 item
和我想要的环境。
退出 ipython 后循环恢复,然后我可以检查下一个 item
和您期望的环境。
有没有办法让我从 ipython 中退出此代码(以便我返回到 shell 提示符)。以任何方式打开另一个外壳并终止进程?
最佳答案
有一个 %kill_embedded
IPython 中的命令。
它不会让您直接返回 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

Are you sure you want to kill this embedded instance (y/n)? [y/N] y
This embedded IPython will not reactivate anymore once you exit.

UPD (06.03.2016): %kill_embedded
功能似乎在 IPython 4.0 中被破坏了;您可以使用 %exit_raise
这将引发异常并返回到 shell。
