Solution Review: Create a Fibonacci Iterator

class Fibonacci:
    def __init__(self, n):
        self.limit = n
        self.count = 1
        self.a = 0
        self.b = 1
    
    def __iter__(self):
        return self
    
    def __next__(self):
        if self.count <= self.limit:    # Controlled iterations
            x = self.a
            self.a, self.b = self.b, self.a +self.b # Adding preceding values
            self.count += 1
            return x
        else:
            raise StopIteration
fib = Fibonacci(7)
iterator = iter(fib)
for x in iterator:
  print(x)
