... method chains: keep



Notes

We'll load in the data via;

import json
import pathlib

poke_dict = json.loads(pathlib.Path("pokemon.json").read_text())

Next well define a new class called Clumper. The idea is that this class will allow us to more flexibly analyse the list of json objects for us.

class Clumper:
    def __init__(self, blob):
        self.blob = blob 

    def keep(self, func):
        return [d for d in self.blob if func(d)]

You can see how it works by running.

Clumper(poke_dict).keep(lambda d: 'Grass' in d['type'])

Can you see a downside with this current approach though?

Feedback? See an issue? Something unclear? Feel free to mention it here.
