Question

Hi!

I'm learning Python and I'm struggling with the following problem. I'm trying to learn Generators, specifically. What would be a pythonic way to perform a calculation from 1 - 300 to list all numbers divisible by 6 and 10 using a list comprehension or generator expression?:

>>>nums = numbers()
>>>iter(nums) == nums
True
>>>next(nums) == 30
True
>>>next(nums) == 60
True
>>>next(nums)
90
...etc.

Here is what I have so far:
def numbers():
i = [x for x in range(1, 301) if x % 6 == 0 and x % 10 == 0]
yield i

Answer 1

def numbers():
    for x in range(1, 301):
        if x % 6 == 0 and x % 10 == 0:
            yield x


nums = numbers()
print(iter(nums) == nums)
print(next(nums) == 30)
print(next(nums) == 60)
print(next(nums))
