Answer 2

Thanks everyone....🙂

Answer 3

Your for loop runs over the positions of your list:

0, 1, 2, 3 and so on, until it's gone.

After you have erased the first element, position 1 (the next position) will be what was originally position 2, because the list is shrinking, while you're moving through it.

[1, 2, 3, 4, 5]
^
0

(erase one)

[2, 3, 4, 5]
^
1

Answer 4

If you start deleting from the end of the list it will work. After last iteration the list a is empty:

a=[1,2,3,4,5]
for i in reversed(a): # <<!!
print(a)
a.remove(i)
print(a)

Answer 5

can anyone elaborate? i actually didn't get the loop concept
