[New-bugs-announce] [issue33235] Better help text for dict.setdefault

[Paddy McCarthy]

New submission from Paddy McCarthy <paddy3118 at gmail.com>:

Hi, I was answering some question and used dict.setdefault as part of the solution and posted the help() on it as part of my answer.

The help was this:

In [15]: help(mapper.setdefault)
Help on built-in function setdefault:

setdefault(...) method of builtins.dict instance
    D.setdefault(k[,d]) -> D.get(k,d), also set D[k]=d if k not in D

This seems the wrong way around. Is it not better expressed as

    D.setdefault(k[,d]) -> set D[k]=d if k not in D and then D.get(k,d)
