while after while

[WildP]

I am new to Python and I am trying to make a program that lets the user input positive numbers. The program should then return a list of the numbers aswell as the number of even numbers in the list. I have written this piece of code.

numbers = []   # An empty list
print('Input positive whole numbers. Stop with zero.')
x = int(input('First number: '))
n = 0
i = 0
while x > 0:
    numbers.append(x)
    x = int(input('Next: '))
print('List:', numbers)    
while i < len(numbers):
    if numbers[i]%2 == 0:
        n += 1
        i += 1
print('Number of even numbers: ', n)

But it only returns the list and not the number of even numbers. Why?
