Catching a non-Exception object (KeyboardInterrupt)

[Michael Goerz]

Hi,

when I try to catch ctrl+c with

except KeyboardInterrupt:

pychecker tells me

Catching a non-Exception object (KeyboardInterrupt)

It works fine, but the message indicates that it's not completely clean.
How should I write the exception correctly?

Thanks,
Michael

Looks like a pychecker bug. It might be confused by KeyboardInterrupt
being derived not from Exception, but from BaseException.

There's a patch for this see:
https://thomas.apestaart.org/thomas/trac/changeset/938?format=diff&new=938
but it looks like pychecker isn't being maintained because nothing has
changed for more than 2 years.

Your code is right; the latest official release of pychecker doesn't
support Python 2.5.
The exception hierarchy has changed a little, now you have BaseException
-> Exception -> all standard exceptions. KeyboardInterrupt and SystemExit
are now direct subclasses of BaseException, not of Exception.
According to the changelog [1] the development version does support 2.5
