Python Python Basics (2015) Shopping List App Second Shopping List App

Is it overkill to put the call to .append() a new item to shopping_list in a try/except block?

In my version I test the input to see if it exists in the shopping_list already. If it does then I reject the input.

I also put the call to .append() a new item within a try/except block. Is that overkill? I mean, are there conditions in which .append() can fail? I understand that if the list in question is actually a set (which consists of unique values only) then .append() could raise an error. But with a regular list is it possible to add something to it that crashes the program?

It does seem a bit overkill; if you have already tested for an acceptable input, I don't see how a passed input would crash append(). I did a quick web search on it and could not find anything that would suggest otherwise.
