Is there a quick & accurate way to test a python install?

[Gene Heskett]

Greetings;

I had an app that is a heavy user of python crash on exit earlier today,
and ever since, the app complains it can't find something in the python
tree, and eventually the app exits.

The leading few lines of the dmesg report are:

Starting LinuxCNC...
redis server started as: 'redis-server ', logging to: /dev/null
(time=1355621147.276382,pid=5133): Registering server on TCP port 5005.

(connection_socket = 3).

KeyError: ('task',)

emcTaskOnce: no Python Task() instance available, using default iocontrol-
based task methods

A configuration error is preventing LinuxCNC from starting.

Then it throws several stanza's of unload messages, culmination in a
SEGMENTATION FAULT.

How can I check & see if my python install if alive?

Thanks.

Cheers, Gene
