Make a function named add_list that takes a list.The function should then add all of the items in the list together and return the total. Assume the list contains only numbers. You’ll probably want to use a for loop. You will not need to use input().
lists = []
def add_list(num):
return (num+)

def add_list(lst):
# Init Total
total = 0
for item in list:
total += item #<-- same as total = total + item
return (total)
You could also cheat a bit by using a function you've not yet learned about: sum()
def add_list(lst):
return sum(lst)

2,564 Pointsyou need to make a function with an iterable parameter. And you need to get the sum of all the items in the iterable.
Try this:
def add_list(iterable): sum = 0 for i in iterable: sum += i return sum
