Remove all empty nested lists

Question

How to from this list:

list = [
    [],
    ['', 'subitem'],
    [[]],
    'item',
    [
        'item',
        'item',
        [''],
        []
    ],
    []
]

I can get this:

list = [
    ['subitem'],
    'item',
    [
        'item',
        'item'
    ]
]

How do I remove recursively all empty nested lists, zero-strings, and lists with nested zero-strings?

Answer 1

Recursion：

def remove_lst(lst):
    if not isinstance(lst, list):
        return lst
    else:
        return [x for x in map(remove_lst, lst) if (x != [] and x != '')]
