# Define your own iteraotr by using __iter__ & __next__ functions.

class OddNumbers:
    def __iter__(self):
        self.a = 1
        return self

    def __next__(self):
        x = self.a
        self.a += 2
        return x


odd_numbers_object = OddNumbers()
iterator = iter(odd_numbers_object)

print(next(iterator))  # 1
print(next(iterator))  # 3
print(next(iterator))  # 5
