Looks good to me (well, I'd write the loop differently, but...). What is
happening that you dislike?

>>> count = sum = 0
>>> number = 1
>>> while number != 0:
... 	number = input('Enter a number: ')
... 	count += 1
... 	sum += number
... 	
[Enters 3, 5, and 7]
>>> sum, count
(15, 4)
>>> count -= 1
>>> sum/count
5
