Suppose we didn't have dict.get(). I would then probably write:
val = mydict[key] if key in mydict else None
Likewise, since we don't have list.get(), I would write:
val = mylist[N] if len(mylist) >- N-1 else None
Neither of those is impractical, but in both cases .get(key) seems to
express the intent in a more obvious way.
That said, it is trivial to write a get() function that does the same
thing... and I've never bothered to do so. In fact, I could write a get()
function that was polymorphic among mappings and sequences with very little
work, which I've also never done. So I guess my case for the huge
importance is undercut :-).
