Issue in Example 2 of Day 13

[jasperhabicht]

In Example 2 of Day 13, it says:

# Filter numbers: let's filter out positive even numbers from the list below
numbers = [-8, -7, -3, -1, 0, 1, 3, 4, 5, 7, 6, 8, 10]
positive_even_numbers = [i for i in range(21) if i % 2 == 0 and i > 0]
print(positive_even_numbers)                    # [2, 4, 6, 8, 10, 12, 14, 16, 18, 20]

But this does not filter the list defined in numbers. It should probably rather be as follows:

# Filter numbers: let's filter out positive even numbers from the list below
numbers = [-8, -7, -3, -1, 0, 1, 3, 4, 5, 7, 6, 8, 10]
positive_even_numbers = [i for i in numbers if i % 2 == 0 and i > 0]
print(positive_even_numbers)                    # [4, 6, 8, 10]

Also, a blank line should be added before this example to separate it from the one above.
