Remove a an 'inner' list inside of a list of dictionaries-CodePudding

I am working with pokeapi lately and im trying to filter some values out of it. The JSON im working on is this one: https://pokeapi.co/api/v2/pokemon/golduck/.

What I need from this is to either find a way to remove the list 'version_group_details' that's inside the big list ['moves'] when the level_learned_at dictionary key has a value of 0 OR when the move_learn_method is NOT level-up. And then create a new list with this information, just with those specific keys and values.

My focus here is to just get a clean list of dictionaries with the moves that have a level-up value that's higher than 0. (I'm trying to make a little table with only abilities learned by level-up).

Any assistance would be appreciated!

editing with the code I have now:

self.moves is just this: https://pokeapi.co/api/v2/pokemon/golduck/


        
        jsonfile = self.moves
        move = jsonfile['moves']
        lst = list(self.__evo_generator(move, 'move'))

        return lst

This would be what 'gets' me the abilities and the following is the generator im calling:

    def __evo_generatortwo(self):

        req = request.Request(
        self.moves,
        data=None,
        headers={
        'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/35.0.1916.47 Safari/537.36'
        }
        )

        with request.urlopen(req) as r:
            data = loads(r.read())

        moves = [
            m['move']['name']
            for m in data['moves']
            if any(d['level_learned_at'] > 0 and d['move_learn_method']['name']=='level-up'
                for d in m['version_group_details'])
        ]
        print(moves)


UPDATED CODE

Up above I updated how the looks, although i am getting the following error: URLError
urllib.error.URLError: <urlopen error unknown url type: {'abilities'>

What could be the cause to this? Or did I make some mistakes when replacing the values with mine?

(I did go with the single list statement option since I don't feel confident enough to mess around with generators, haha)

CodePudding user response：

If you just need any move that could be learned by leveling up, at any level (except 0) and without additional constraints:

from json import loads
from urllib import request

req = request.Request(
    'https://pokeapi.co/api/v2/pokemon/golduck/',
    data=None,
    headers={
        'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/35.0.1916.47 Safari/537.36'
    }
)

with request.urlopen(req) as r:
    data = loads(r.read())


def __evo_generator(moves):
    for m in moves:
        if any(d['level_learned_at'] > 0 and d['move_learn_method']['name']=='level-up' for d in m['version_group_details']):
            yield m['move']['name']


for m in __evo_generator(data['moves']):
    print(m)

Note that I've removed the self, since you didn't provide the rest of the code of the class, but you can of course turn the function into a method. And since the key is really a two-parter ('move' and 'name'), I've left it out, but you could add that back in.

I wrote the function as a generator, since that was the route you were on, but you could also get the moves as a list in a single statement:

moves = [
    m['move']['name']
    for m in data['moves']
    if any(d['level_learned_at'] > 0 and d['move_learn_method']['name']=='level-up'
           for d in m['version_group_details'])
]
print(moves)

Edit: The first code example in the answer is intended to run all by itself, however in your original code, you probably only need the __evo_generator generator, or the second bit of code instead of it.
