+Write an iterator that returns the fibonacci series. Your implementation should be pretty short!

+class FibIterator(object):
+
+ def __init__(self):
+ self.prev, self.current = 0, 1
+
+ def __next__(self):
+ current = self.prev
+ self.prev, self.current = self.current, self.prev + self.current
+ return current

+ In this problem, we note that we are making an iterator so we’re going to need at least two elements, maybe three. We for sure will need an __init__
method to set up our problem. We also need an __iter__
method that returns an object that implements the __next__
method. In our __init__
function, we are simply initializing our variables so that we have values to work with. In our __iter__
method, we’re following the rules and returning an object that implements the __next__
method. Since the object that we’re creating has the __next__
method, we’re good to go! Lastly, we create the __next__
method that stores the current value, updates our variables, then returns that value that we stored from the beginning.
