defining user exceptions

[CSUIDL PROGRAMMEr]

I am trying to write a user defined exception that will catch for
failed dependencies when a rpm is installed

try:
rpm -ivh xxx.rpm --force;
except RPMError:
print RPM failed dependency


Can some one tell me how to define this RPMError. I looked at python
docs but they were not useful.

That takes care of the literal question... But totally ignores that
the only things that are Python in the sample is the "try:" statement.

The "print" is close, since it needs quotes around the string.

But the "rpm..." call is not a Python statement, and will likely
generate something about a syntax error.

And, once the "rpm..." is embedded in an os.system() or subprocess.*
call, one has to parse the error messages produced by the external
program to determine if there is a failure...
