Create a list of Niven numbers in Python

+3
−4

There's this new challenge on Code Golf CD and I'm using Python to do it. A little bit of golfing already took place, so the code might look a bit messy for you. Anyway, I'm proud of what I've written so far:

def g(n):
	s=0;t=n
	while t>0:s+=t%10;t//=10
	return n%s==0

def f(n):
	a=[]
	for i in range(1,n+2):
		while not g(i):
			i+=1;continue
		a.append(i)
	return a

First function checks for Niven numbers, the second one creates a list for them. Problem that occurred is something like this since I can't word it.

If I'd input 14 into the function, I should get:

[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 18, 20, 21, 24]

But instead, I'd get this:

[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 12, 18, 18, 18]

Any ways to fix this?

The lists are one element to long I think. If you input 14 you should get 14 elements, not 15.
