itertools.cycle().next()?

Question

Well, I was using itertools.cycle().next() method with Python 2.6.6, but now that I updated to 3.2 I noticed that itertools.cycle() object has no m

Answer 1

iter.next() was removed in python 3. Use next(iter) instead. So in your example change itertools.cycle().next() to next(itertools.cycle())

There is a good example here along with various other porting to python 3 tips. It also compares various other next() idioms in python 2.x vs python 3.x

Answer 2

In Python 3.x, iterators don't have it.next() any more. use next(it) instead, which also works in Python 2.6 or above. Internally, this will call it.next() in Python 2.x and it.__next__() in Python 3.x.
