[IPython-dev] exit() in a Spyder script

[Carlos Córdoba]

Hi,

We (the Spyder team) didn't want to wash our hands and transfer the 
problem to the IPython one :-) The thing is if you're calling exit(), 
you want the Python interpreter to terminate, and Spyder can't control this.

However, I found an easy solution, following your suggestion about ask_exit:

1. Define a pass function like this:

     def f(): pass

2. Run this code in the IPython console:

     In [1]: ip = get_ipython()

     In [2]: ip.ask_exit = f

Then exit() won't have any effect.


If you want this code to always evaluate for any IPython Console in 
Spyder, you need to go to:

     Preferences > IPython Console > Startup > Run code

and paste this line in the "Lines" text field:

     def f(): pass, get_ipython().ask_exit = f


Cheers,
Carlos
