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.
list1=[1,2,3]
sum_of_list=0
for num in list1:
sum_of_list = sum_of_list + num
return sum_of_list
def summarize(list1):
sum_of_list=0
for num in list1:
sum_of_list = sum_of_list + num
return "The sum of {} is {}.".format(str(list1),str(sum_of_list)
``` PLUS

Your white space is off in the summarize function as well as missing a parenthesis.

```def summarize(list1):
sum_of_list=0  # one too many spaces here
for num in list1:
sum_of_list = sum_of_list + num
return "The sum of {} is {}.".format(str(list1),str(sum_of_list) # missing a parenthesis to close format()
```

Thank you very much Michael. Much appreciated.
