How to use

Let's start with a dictionary

pikachu = {
  "name": "pikachu",
  "moves": [
    {
      "move": {
        "name": "mega-punch",
        "url": "https://pokeapi.co/api/v2/move/5/"
      }
    },
    {
      "move": {
        "name": "pay-day",
        "url": "https://pokeapi.co/api/v2/move/6/"
      }
    },
    {
      "move": {
        "name": "thunder-punch",
        "url": "https://pokeapi.co/api/v2/move/9/"
      }
    }
  ],
  "stats": [
    {
      "base_stat": 90,
      "effort": 2,
      "stat": {
        "name": "speed",
        "url": "https://pokeapi.co/api/v2/stat/6/"
      }
    },
    {
      "base_stat": 50,
      "effort": 0,
      "stat": {
        "name": "special-defense",
        "url": "https://pokeapi.co/api/v2/stat/5/"
      }
    }
  ]
}

apply_keyed

from handy_dict import apply_keyed

With handy-dict you can apply a function to the keys inside a dictionary, say you want to take name out of stat, go from something like this:

{
  "base_stat": 50,
  "effort": 0,
  "stat": {
    "name": "special-defense",
    "url": "https://pokeapi.co/api/v2/stat/5/"
  }
}

to this:

{
  "base_stat": 50,
  "name": "special-defense"
}

The function transform_stat is just a little helper that will transform the stats array in our pikachu dictionary and return a new array, that will replace the stats in a copy of the original dict:

def transform_stat(stat_array):
    return {
        stat["stat"]["name"]: stat["base_stat"] 
        for stat in stat_array 
    } 

modified_pikachu = apply_keyed(pikachu,["stats"], transform_stat)
modified_pikachu["stats"]

{'speed': 90, 'special-defense': 50}

return_keyed

from handy_dict import return_keyed

handy-dict also makes it easy to return multiple values from a dictionary, iterating through keys and arrays:

return_keyed(pikachu, ["moves","move","name"])

['mega-punch', 'pay-day', 'thunder-punch']
