3,678 PointsSummation from a python list
I can't see my error, I'm trying to add the integers passed in from the list.
Alternatively I tried using the sum() function but could not pass the test:
def add_list(numlist):
total = sum(numlist)
return total
[MOD: added ```python formatting -cf]

def add_list(lst):
count = 0
for item in lst:
count = count + item
return count
