        }
    ]
}
print(deep_find(user, 'pokemons.*.name'))
# output: ['pikachu', 'charmander']

Find the first non-null result

from deepfinder import deep_find
user: dict = {
    'name': 'ash',
    'pokemons': [
        {
            'name': 'pikachu',
        },
        {
            'name': 'charmander',
            'ball': 'superball'
        }
    ]
}
print(deep_find(user, 'pokemons.?.ball'))
# output: 'superball'

Find all non-null results

from deepfinder import deep_find
user: dict = {
    'name': 'ash',
    'pokemons': [
        {
            'name': 'pikachu',
        },
        {

        }
    ]
}
print(deep_find(user, 'pokemons.*?.ball'))
# output: ['superball', 'ultraball']

Use custom dict and list

from deepfinder.entity import DeepFinderDict
user: dict = DeepFinderDict({
    'name': 'ash',
    'pokemons': [
        {
            'name': 'pikachu'
        },
        {
            'name': 'charmander',
            'ball': 'superball'
        }
    ]
})
print(user.deep_find('pokemons.?.ball'))
# output: 'superball'

from deepfinder.entity import DeepFinderList
users: list = DeepFinderList([{
    'name': 'ash',
    'pokemons': [
        {
            'name': 'pikachu'
        },
