Getting data from api in json format into a python dictionary

It's an unusual question that does not stem from my coursework here, but maybe someone can help me think through this.

I have to get information from an api and catch it in a python dictionary. The api is a url plus a page number. I will then use that dict to get information to a database, which I am pretty sure I can do. I am looking for the best way to get a few key-value pairs from the json format to do that.

Can I capture specific key-value pairs? Should I get all of it in a dict? And am I doing it the right way? (I am getting the full load in a dict, but it's full of data I dont need!)

import mysql.connector
import requests
import json

# I need a dictionary to catch all the names, id, weight and height in.\
pokemon = {}
poke_url = "https://pokeapi.co/api/v2/pokemon/"
print(poke_url)

poke_page = 0
for number in range(0,151):
    poke_page += 1
    answer = requests.get(poke_url + str(poke_page))
    pokemon_tabel = json.loads(anwer.text)

for item in pokemon_tabel:
    name = pokemon_tabel.get("name")
    weight = pokemon_tabel.get("weight")
    height = pokemon_tabel.get("height")
    poke_id = pokemon_tabel.get("id")

# connect met db / or create one

# create table 

# insert data in table

#commit and close connection to database - commented out for now
#mydb.commit()
#mydb.close

Thanks for looking at this! All help appreciated :)

If just looking to limit the unwanted data and you know the specific items you wish, say, by name, you could add a check after the name assignment:

if name not in accepted_list:
    # continue for loop with next item
    continue

the define accepted_list before the for loop.

you could add other selections based on the other attributes weight, height, poke_id

Post back if you need more help. Good luck!!!

Thanks! I ended up doing it way way differently, though. I created a new dictionary in the loop for all the key-value pairs I needed and inserted that single dictionary into the database before looping again and creating a new dictionary with new key-value pairs. It was not elegant, but in the end it worked.
