AttributeError: 'generator' object has no attribute 'next' code example

Example: AttributeError: 'generator' object has no attribute 'next'

In pythpn 3.x, there is no longer a .next method attached to iterator; 
If you have a function that returns an iterator, call the function and pass the result to the next() function

next(anIterator)
next(a_function_that_returns_an_iterator())
