TypeError: 'int' object is not iterable

Question

I am trying to have a program look inside multiple lists to see if there are multiple integers in those lists. I received an answer on a previous question I asked to accomplish

Answer 1

Here is your matrix, from an earlier question

matrix = [
    [0, 0, 0, 5, 0, 0, 0, 0, 6],
    [8, 0, 0, 0, 4, 7, 5, 0, 3],
    [0, 5, 0, 0, 0, 3, 0, 0, 0],
    [0, 7, 0, 8, 0, 0, 0, 0, 9],
    [0, 0, 0, 0, 1, 0, 0, 0, 0],
    [9, 0, 0, 0, 0, 4, 0, 2, 0],
    [0, 0, 0, 9, 0, 0, 0, 1, 0],
    [7, 0, 8, 3, 2, 0, 0, 0, 5],
    [3, 0, 0, 0, 0, 8, 0, 0, 0],
    ]

And here is the methods:

def all_num_in_list(d, numbers):
    for n in numbers:
        if n not in d:
            return False
    return True

def all_num_in_any_list(lists, numbers):
    for d in lists:
        if all_num_in_list(d, numbers):
            return True
    return False

And since you in an earlier question used the numbers, 3,5 and 6 as examples to look at, here is how you check if these numbers are in the matrix above:

all_num_in_any_list(matrix, [3, 5, 6])

Which will return False, as none of the lists in your list of lists will have all these tree numbers, while for example:

all_num_in_any_list(matrix, [0, 1, 9])

will return True, as there is a list that includes these numbers.
