Help.... Why does placement of variables affecting output?

Question

Just started learning python. I'm so sorry if this question is asked before but why the 2 cases produced different results?
Case 1:
total = 0
for i in range(1, 5):
total += i
print(total)

Output = 10

Case 2:
for i in range(1, 5):
total = 0
total +=i
print(total)

Output = 4

Answer 1

In the second case total is reset to 0 every time the loop runs, except the last time when you exit the loop, so it actually stores the last number you looped on, which was 4

Answer 2

I see...
Thanks a lot!
