Indexable get method. [1,2,3].get(4) # None

I don’t see dict.get in the same vein here because it is useful for algorithms that do expensive things with potentially large dicts like the polynomial example I showed above.

@oscarbenjamin

p = p1.copy()
for k, v in p2.items():
    v = p.get(k, 0) + v
    if v:
        p[k] = v
    else:
        del p[k]
return p

No one uses dict like that. Can you point to anything like this in any library? At least 2 examples.

Also, why dict.get? Why not try-except statement?
