Why does it give 6?

Question

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

print(n)

Answer 1

Because you are printing n after the end of the for loop.
n will be equal to the last element in the A list wich is the last element you have append (abs(-6))

Note that A will be equal to [8,0,-4,-6,1,4,6] when the loop is end.

Answer 3

The code in the for loop appends 4 and 6 to A. That makes 6 the last value in A and after the last iteration of the loop n is the last value in the A.
