Do you mean to catch every possible exception when importing aModule?
If you replace "except:" with "except ImportError:" then only actual
import errors will be caught. Any other errors in aModule (such as syntax
errors, etc. will still raise a exception as normal.

If importing aModule is unnecessary, then just don't import it.
What are you trying to protect against?
