They want you to create another function called "summarize" - it is not a variable it's a function. This function should return a string using string formatting, and it will use the other function you made as well.

Let me know if you want more hints.

I did as you said (if I have got you right!) but it still doesn't return the right answer. can you take a look please?

total = 0 also tried with "total = int() " list = [1, 2, 3] def summarize(item): return(total+item)

def add_list(list): for item in list: summarize(item) return(total)

add_list(list)

It says it returns 0! , but the answer should be 6.
