Retrieve weekly eia inventory data to update my csv directly

alkp

This is my first part of script that should retrieve the latest data?

cell 1

import lseg.data as ldld.open_session(app_key="app-key").open()

cell 2

from lseg.data.content import historical_pricing as hp
from datetime import date
import os

1. Correct RIC for total commercial crude stocks

crude_rics = ["C-STK-T-EIA"]

2. Date range

start_date = "2020-01-01"
end_date = str(date.today())

3. Fetch data

response = hp.summaries.Definition(
universe=crude_rics,
interval=hp.Intervals.WEEKLY,
start=start_date,
end=end_date
).get_data()

4. Extract and rename

raw_df = response.data.df
print("Latest date returned:", raw_df.index.max())
print("Today's date:", date.today())

comm_last_df = raw_df[["COMM_LAST"]].copy()
comm_last_df.columns = ["TotalCrude"]

5. Save

os.makedirs("../data", exist_ok=True)
comm_last_df.to_csv("../data/crude_total_stocks.csv")
print("Saved:", os.path.exists("../data/crude_total_stocks.csv"))
