Helping with a research project that involves downloading all the stock symbols in nasdaq_screener.csv using the alpha vantage API.
The notebook shows how to download the data synchronously, while the data_dump.py file will download the data using multiprocessing (unless the API limit gets hit). calc_years.py calculates the years of data available for all stocks. This is then dumped into year_calc_combined.csv and appended to nasdaq_years.csv.
