Why the right answer of the code showed in the description is 6 (I take it from a challenge)

Question

What is the output of this code?

A = [8, 0, -4, -6, 1]
for n in A:
if n < 0:
A.append(abs(n))
x = n
print(x)

Answer 1

n = 8
n < 0 False
.
.
.
n = -4
n < 0 True
A becomes [8, 0, -4, -6, 1, 4]
n = -6
n < 0 True
A becomes [8, 0, -4, -6, 1, 4, 6]
Then there are no more negative values, the last value of A Is 6, so x = 6

Answer 2

Thanks man I got it :)
