g = [(yield i) for i in range(3)] Currently, this makes `g` into a generator, not a list. Everybody seems to agree this is nonintuitive and should be changed. One proposal is to make it so `g` gets assigned a list, and the `yield` happens in the enclosing scope (so the enclosing function would have to be a generator). This was the way things worked in Python 2, I believe. Another proposal is to make this code a syntax error, because it's confusing either way. (For what it's worth, that would be my preference.) There is related discussion about the semantics of list comprehensions versus calling list() on a generator expression, and of async semantics, but I don't think there's any clear point of action there. > -- > --Guido van Rossum (python.org/~guido) > > _______________________________________________ > Python-Dev mailing list > [email protected] > https://mail.python.org/mailman/listinfo/python-dev > Unsubscribe: https://mail.python.org/mailman/options/python-dev/ > jelle.zijlstra%40gmail.com > >
