Can u please explain this code

Question

def func(x):
res = 0
for i in range(x):
res += i
return res

print(func(4))

Answer 1

0+0+1+2+3
output 6

Oh no, return is in for loop
So 0+0
Output 0

At first iteration, exit the function with return

Answer 2

The return statement seems to be wrongly indented, it should be on the level of for.

If that is given:

The last line calls the function func, passing 4 as an argument.

The loop adds every value in 0, 1, 2, 3 (range(4)) to res, then res gets returned.

Result: 6.

With the mistake: Always 0.

Answer 3

It's not wrongly indented
It's just a tricky quiz 🤣
