# Python Code Challenges: Loops Nr. 1

**Hi there everyone! **

I have a brief questions regarding challenge nr. 1 in Python Code Challenges (Optional). The challenges asks you to create a loop through a list and only return those divisible by ten. I failed multiple time at a single step, namely:

In the solution there is onlye extra step added before returning the count/list, which is count =+1. Can someone explain to me why this needs to be added and why I get an error, if it is not included? Thank you all very much in advance <3

I donâ€™t know the exact text of the challenge. But based on the screenshot you posted, the argument/input being passed to the function is a list. The function isnâ€™t supposed to return the list of numbers which are divisible by 10. Instead, the function is supposed to return how many numbers of the list are divisible by 10.
e.g. `divisible_by_ten([1, 10, 60, 5, 8, 90, 3])` should return `3` because there are three numbers in the list that are divisible by ten.
`count += 1` is equivalent to `count = count + 1`
It is necessary to increase the count by one every time a perfectly divisible number is observed. Once the loop finishes, the count is returned.
