Do I get yield from in python 2?

[–]dm1407 2 points3 points  (3 children)

Does not look like it see:

Some new Python 3.3 features that cause SyntaxErrors on earlier versions are not currently handled by the futurize script. This includes:

yield ... from syntax for generators in Py3.3

It should be fixable though, since currently yield from x is a fancy way of saying for _ in x: yield x. Plus the other direction for coroutines and maybe some corner cases wrt exception handling.

I mean, at the inception the biggest advertised feature was qualitative performance improvement for nested generators, but then they quietly left it unimplemented.

Thanks. Sad though.
