Answer 1

According to me
In list elements↓
A total 6
B total 5

See you for loop will only repeat the condition till it takes so it is going to repeat the process

When you print because of -1 condition it take the second number as repetition because for loop has to complete the number of round it has been said

Answer 2

if you run this, you will see what is going on:

a = [0, 1, 2, 3, 4, 5]
for a[-1] in a:
print(a[-1])
print(a)
