Could someone explain how the all() function work in this scenario

Question

list2 = [“apples”,”pear”,”cookie”]
list1 = [“apples”,”pear”,”cookie”, “popcorn”, “candy”]
Check = all(item in list1 for item in list2)

If Check:
   print(“items in list2 is also in list1”)

Im confused on how exactly the all(item in list1 for item in list2) works and i was wondering if someone could explain the process taking place

@cards that is incorrect. It does not check all conditions, and certainly it does not do it simultaneously. — matszwecja, Apr 27 '22 at 12:43
`all` return `True` if all statements are __simultenously__ `True`. If a `False` is met then return `False` — cards, Apr 27 '22 at 12:51

The equivalent form of all in Python:

def all(iterable):
    for val in iterable:
        if not val:
            return False
    return True

Because you are passing a generator, it will yield the value of item in list1 for each item in list2 one by one, so it is iterable.
