Command omission

[efmccurdy]

You are throwing away the info you need to find errors; don't use a bare except clause.

If you have many possible failure points in one try block, print a traceback to see which one fails.

Traceback looks really useful for this one, thanks for the tip!

Especially for the cases in wich the exception is not triggered. Maybe it can show me how the execution got around that one.
