Question

Im trying to flatten out the following list in python code. I keep running into an 'int is not iterable error' i know this is due to the list being both strings and ints. how do i account for this? 


list_1 = [1,2,[3,[4,5],6],7,8,['hardware'],[['software'], 'interface']]


def flatten (list):
    flat = []
    for sublist in list_1:
        for item in sublist:
            flat.append(item)

    print(flat)
    return


flatten(list_1)

Answer 1

list_1 = [1, 2, [3, [4, 5], 6], 7, 8, ['hardware'], [['software'], 'interface']]


def flatten(list_1):
    if type(list_1) == list:
        lst = []
        for item in list_1:
            lst.extend(flatten(item))
        return lst
    else:
        return [list_1]


print(flatten(list_1))
