No, no, no; never use a bare except! :)
can you explain why? i can't think of any reason why the code would be
better catching a specific exception.
as a general rule, maybe, but in this particular case i can't see a reason
- so i'm not sure if you're just pedantically following rules or if i've
missed something i should know.
What if the user pressed ctl-c right when the float was being converted
and appended?
Never use a bare except unless you have a specific reason to do so,
and there are very few of those. (Yes, I should have said it that way
to start with, my apologies for going hyperbolic.) Using because it
doesn't _look_ like it will cause issues is just asking for hard to
track down bugs :).
