I don't get it.
How are you going to implement this feature?
This exception can happen in anywhere depends on the timing you press ^C
You can try it a little more times then you will know.
It's just like you cancel the program even before it starts.
Just like u type ipython and press ^C before the prompt shows up.

Can @pi314 reply my question above? I really want to know how to do it.
The pic you gave above showed the KeyboardInterrupt happened while importing the argparse module.

The most closed solution I can imagine is that we add a singal handler in the scripts/zdict even before the line from zdict import zdict but I don't think it's a good solution.

@M157q: Well, I was going to catch exceptions on zdict.lookup(), but I didn't found that my screenshot shows it explode on argparse
