When you have a Try-Catch for an error, but you have no implementation of what should happen
when an error is caught.
try:
do_something_that_might_throw_exception()
except Exception:
passAs you can see, the exception is not handled, logged, or notifies the user of such exception.
(found from The Diaper Pattern Stinks)
You would not know what is happening in the background of your program. It might range from memory leaks to simple errors and warnings.
At the very least, log the exception, notify the user, or insert code that will handle the issues at run-time.
