Increment and Decrement in Python

Is the increment/decrement step comes after/before the print function

my_list=[1,2,3,4,5,6,7,8,9]
sum=0
index=0
while sum<10:
    sum+=my_list[index]
    index+=1
    print(sum)

>Solution :

The body of the while is executed from top to bottom. You first tried to increment the value of sum by the value of the first index of the my_list then you printed the sum. If you want to see the 0 as your first output, you have to do the printing first.

my_list = [1, 2, 3, 4, 5, 6, 7, 8, 9]
sum = 0
index = 0
while sum < 10:
    print(sum)
    sum += my_list[index]
    index += 1

output:

0
1
3
6

Also do not use built-in names(here sum) as your variable names.
