This can be done fairly easily by creating a module (lets call it interactive) with the following code in it. ----------- import sys,os
def debug_exception(type, value, traceback):
# Restore redirected standard I/O
sys.stdin = sys.__stdin__
sys.stdout = sys.__stdout__
sys.stderr = sys.__stderr__ # Kick the interpreter into interactive mode and call the original
# exception handler.
os.environ['PYTHONINSPECT'] = '1'
sys.__excepthook__(type, value, traceback)sys.excepthook = debug_exception -----------
Now if you import this module and raise an unhandled exception, you will be in interactive mode. In other words, I think the following script does what you are asking for.
----------- import interactive
raise RuntimeError('Interactive Mode')
-----------This also has the advantage that if there are no unhandled exceptions in your script, the script runs and terminates normally.

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!

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 :)

Joe a écrit :
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.
