Json data & List Comprehension

I need more practice on list, dictionary comprehension with real world Json data. Figuring out data structure was difficult as data itself is very complicated.

APIs

When using APIs, first thing to do is to read documentation thorougly for parameters that can provide the best output.

import requests

from twilio.rest import Client

STOCK_NAME = "TSLA"
COMPANY_NAME = "Tesla Inc"
STOCK_ENDPOINT = "https://www.alphavantage.co/query"

api_key_news = "42303e22cff34ed383e996fb72de51b8"

parameters = {
    "function": function,
    "symbol": symbol,
    "apikey": api_key_stock
}

response = requests.get(url=STOCK_ENDPOINT, params=parameters)
response.raise_for_status()
data = response.json()
print(data)

print(data["Time Series (Daily)"]["2021-01-15"]) #hard coded, but can use list comprehenshion
day15 = data["Time Series (Daily)"]["2021-01-15"]
day15_closing_data = [price for (num, price) in day15.items()]
day15_closing = day15_closing_data[3]
print(day15_closing)
# yesterday = data["Time Series (Daily)"]["2021-01-15"]["4. close"]
# print(yesterday)

day19 = data["Time Series (Daily)"]["2021-01-19"]
day19_closing_data = [price for (num, price) in day19.items()]
day19_closing = day19_closing_data[3]
print(day19_closing)

difference = abs(float(day19_closing) - float(day15_closing))
rounded_dif = round(difference, 2)
print(rounded_dif)
percentage_dif = rounded_dif/float(day19_closing)*100
round_per_dif = (round(percentage_dif, 2))

if percentage_dif >= 2:
