Using an iterator in python? -

i have learned iterators in python having hard time implementing them.

i trying write class loop works:

  odds = oddnumbers(13)   in odds:       print(i)  

i want write iter() function , next() function this.

so far have:

class oddnumbers:      def __init__(self, number):         self.number = number      def __iter__(self):         return self      def __next__(self):         current = self.number         if self.number%2 == 0:             return current         else:             raise stopiteration 

but @ moment returning nothing. expect output be

1 3 5 7 9 11 13 

help?

you need variable track current number:

def __init__(self, number):     self.number = number     self.current = 1 

then need compare ending number, , maybe increment it:

def __next__(self):     if self.current > self.number:         raise stopiteration     current = self.current     self.current += 2     return current
