# I'm stuck.

I can't seem to figure out what I did wrong. See functions.py for my code. I keep getting this message "Bummer! summarize returned the wrong output. Got 'The sum of 6 is 6' instead of 'The sum of [1, 2, 3] is 6.'."

functions.py
```# add_list([1, 2, 3]) should return 6
# summarize([1, 2, 3]) should return "The sum of [1, 2, 3] is 6."
# Note: both functions will only take *one* argument each.
total = sum(num)

def summarize(fun):
return "The sum of {} is {}".format(num,total)

If you change that to the value that's given to the summarize function, you will see that the code now works! Hopefully I explained it good enough for you to understand :)

```def add_list(num):
total = sum(num)

def summarize(fun):
