问题描述
因此，我正在运行一个Python脚本，在其中编写以下代码来调用Python的调试器PDB:
So I am running a Python script within which I am calling Python's debugger, PDB by writing:
import ipdb; ipdb.set_trace()
(iPython的PDB版本，尽管就此而言，我认为这没有什么区别；我仅将其用于彩色输出).
(iPython's version of PDB, though for the matter I don't think it makes a difference; I use it for the colored output only).
现在，当我进入调试器时，我想执行一个多行语句，例如if子句或for循环，但是只要我键入
Now, when I get to the debugger I want to execute a multi-line statement such as an if clause or a for loop but as soon as I type
if condition:
并按回车键，我收到错误消息*** SyntaxError: invalid syntax (<stdin>, line 1)
and hit the return key, I get the error message *** SyntaxError: invalid syntax (<stdin>, line 1)
如何在PDB中执行多行语句?如果不可能，是否有办法解决仍然执行if子句或for循环的问题?
How can one execute multi-line statements within PDB? If not possible is there a way around this to still executing an if clause or a for loop?
推荐答案
您可以在pdb中执行此操作，以使用所有可用的本地变量启动临时的交互式Python会话:
You could do this while in pdb to launch a temporary interactive Python session with all the local variables available:
(pdb) !import code; code.interact(local=vars())
Python 2.6.5 (r265:79063, Apr 16 2010, 13:57:41)
[GCC 4.4.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
(InteractiveConsole)
>>>
完成后，使用Ctrl-D返回常规pdb提示符.
When you're done, use Ctrl-D to return to the regular pdb prompt.
只需不按Ctrl-C，这将终止整个pdb会话.
Just don't hit Ctrl-C, that will terminate the entire pdb session.
