How to get one value from a generator in Python?

Very basic question - how to get one value from a generator in Python?

So far I found I can get one by writing gen.next(). I just want to make sure this is the right way?

Thanks, Boda Cydo.

From stackoverflow

• This is the correct way to do it.

  You can also use next(gen).

  http://docs.python.org/library/functions.html#next

• Yes, or next(gen) in 2.6+.

• In Python <= 2.5, use gen.next(). This will work for all Python 2.x versions, but not Python 3.x

  In Python >= 2.6, use next(gen). This is a built in function, and is clearer. It will also work in Python 3.

  Both of these end up calling a specially named function, next(), which can be overridden by subclassing. In Python 3, however, this function has been renamed to __next__(), to be consistent with other special functions.
