As i am being asked to print out every item in the list "items" I don't understand why the correct code is print(item) and not print (items).if iprint item, won't I just get 1 item of the list?
def loopy(items):
# Code goes here

Items is an iterable meaning you can loop through it. If my basket called items has 6 fruits ["apples","bananas","grapes","oranges","strawberries","watermelon"], and i wanted to print out each fruit I would say like below
for item in items:
print(item)
# the output would be
apples
bananas
grapes
oranges
strawberries
watermelon
hope this helps

2,837 PointsAndreas, thxs for your answer. I will take it as just the way it is. Even though it seems illogical. If I am going to loop through many things, it seems more logical to say print (items), i imagine print(item) will only print 1 item. And is items some reserved name? What if I said print (object) would i get anything.?

Depends what you are trying to achieve. Yes you can print items which will return a list like so ['apples' 'bananas','grapes','oranges','strawberries','watermelon']. But what if i said to you Didier only print out fruits that are less than 8 characters, that's where loops comes in when you need to evaluate each item in a list.
for item in items:
if len(item)< 8:
print(item)
else:
continue
# my experience you will almost always have to loops around lists to evaluate each item or row.
Hope this helps
