How does this Python code work?

Question

n = 10

# initialize sum and counter
sum = 0
i = 1

while i <= n:
sum = sum+i
i = i+1 # update counter

print("The sum is", sum)

Answer 1

There are 10 iterations in total from i=1 till i=n, where n is 10. Each time you add the value of i to the variable sum.
So it is 1+2+3+...+10 which is 55.

Answer 2
