python -i（交互式环境） [英] python -i (interactive environment)
问题描述
当您运行python -i scriptname.py时在脚本完成后，您在交互式命令提示符处离开了
。
有没有办法从正在运行的程序中发生这种情况？
换句话说，我可以运行scriptname.py（不是python -i scriptname.py）
和scriptname.py里面我决定我要回到
交互式提示？
我已经搜索过，到目前为止，我唯一想到的就是使用pdb，但是
与交互式提示不完全相同。
有没有办法做到我错过了？
谢谢。
When you run "python -i scriptname.py" after the script completes you left
at the interactive command prompt.
Is there a way to have this occur from a running program?
In other words can I just run scriptname.py (NOT python -i scriptname.py)
and inside of scriptname.py I decide that I want to fall back to the
interactive prompt?
I''ve searched and so far the only thing I''ve come up with is to use pdb, but
that is not exactly the same as the interactive prompt.
Is there any way to do it that I have missed?
Thanks.
推荐答案
很简单就是你在UNIX上...
你juste必须放在你文件的开头：
＃！/ usr / bin / python -i
它和juste做了什么你想要:)

Very simple is you''re on UNIX ...
You juste have to put at the beginnin of your file :
#!/usr/bin/python -i
And it juste does what you want :)

嗨皮埃尔，
感谢您的回复，但我不是在Unix上，即使我是那个
解决方案，它也达不到预期的效果。
我希望脚本决定是否回退到交互式提示符。
您的解决方案使其始终回退到交互式提示符。
我想做点什么ike：
试试：
＃执行代码
除了MyExceptionOccurred，except_msg：
＃fall交互式提示。
换句话说，我想让我的程序确定是否显示
交互式提示。
谢谢！

Hi Pierre,
Thanks for the reply, but I am not on Unix and it even if I was that
solution it does not achieve the desired results.
I want the script to decide whether to fall back to the interactive prompt.
You solution makes it ALWAYS fall back to the interactive prompt.
I want to do something like:
try:
# execute code
except MyExceptionOccurred, except_msg:
# fall to interactive prompt.
In other words I want to have my program to determine whether the
interactive prompt to be displayed or not.
Thanks!

你的解决方案使它总是回到交互式提示。

实际上，使用sys.exit（）意味着即使使用了python -i
，程序也可以退出。
你可以使用：
导入代码
code.interact（）
模拟交互式提示。

Actually, using sys.exit() means the program can exit even if python -i
is used.
You can use:
import code
code.interact()
which emulates the interactive prompt.
