# Python Core 27.2 "Iteration"

I'm not sure what to do here: for loops allow you to easily iterate through lists. Given a list of numbers, output their sum. Sample Input 1 3 7 5 Sample Output 16 Output the sum after the loop. list = [1, 2, 3, 4, 5, 6, 7, 8, 9] sum = 0 #your code goes here

to solve this task, you need the following steps: (there a various ways to do this task, this is one of them):
1 - as the input values has to be given in one line, the input has to be spit to individual elements to a list
2 - create a variable that can hold the running sum of the values in the list
3 - use a loop to iterate through the list (numbers are still strings)
4 - in each loop iteration you will get one value, that has to be converted to int and added to the sum variable
5 - after last iteration loop, the variable holds the sum of all numbers
6 - print the result of the variable
happy coding and good success!

You have to give the sum of the every value inside the list.
For this, according to the question you have to use a loop.You can iterate each value of the list using loop like that.
Like that,
for i in list:
...
Now try it by yourself.

list = [1, 2, 3, 4, 5, 6, 7, 8, 9]
sum = 0
#your code goes here
for i in list:
if int(i):
sum += 1
print(sum)
My output: 9
