What am I missing to make this function work? Hint? Thanks in advance...
def add_list(num):
for num_list in add_list:
num_list.append(num)
return sum(num_list)

Treehouse Guest TeacherWhere did the add_list in your for loop come from? To solve this one, there's two general approaches. One, just use sum() on the list that's passed in (your function takes that as the argument num) and return that. Two, make a new total (or whatever) variable that's assigned to 0. Then, for each number in the list, add that number to total. Then return total at the end.

Courses Plus Student 36,143 PointsI was struggling with this because you've given a lot of autonomy here compared to the shopping list exercise. I'll be back to it very soon. Little by little I will finish this course. I am taking for credit community college classes in coding and website design. Treehouse is enormously helpful...
BTW my shopping list had: eggs, bacon, spam, spam, spam, spam, spam, Lobster in a butter garlic reduction sauce and spam. (Once I got the SHOW to stop popping up....) NJM

Treehouse Guest TeacherThere is definitely a lot of autonomy. Glad you're making your way through it!
