So I have been following a youtube tutorial on Python finance and since Yahoo has now closed its doors to the financial market, it has caused a few dwelling problems.

I run this code

    import bs4 as bs
import datetime as dt 
import os
import pandas as pd
import pandas_datareader.data as web
import pickle
import requests
from pandas_datareader import data as pdr
import fix_yahoo_finance as yfdef save_sp500_tickers():resp = requests.get('https://en.wikipedia.org       /wiki/List_of_S%26P_500_companies')soup = bs.BeautifulSoup(resp.text, "lxml")table = soup.find('table', {'class':'wikitable sortable'})tickers = []for row in table.findAll('tr')[1:]:ticker = row.findAll('td')[0].texttickers.append(ticker)with open("sp500tickers.pickle", "wb") as f:pickle.dump(ticker, f)print(tickers)return tickers# save_sp500_tickers()def get_data_from_yahoo(reload_sp500=False):if reload_sp500:tickers = save_sp500_tickers()else:with open("sp500tickers.pickle", "rb") as f:tickers = pickle.load(f)if not os.path.exists('stock_dfs'):os.makedirs('stock_dfs')start = dt.datetime(2000, 1, 1)end = dt.datetime(2017, 8, 24)for ticker in tickers:if not os.path.exists('stock_dfs/{}.csv'.format(ticker)):data = pdr.get_data_yahoo(ticker, start, end)df.to_csv('stock_dfs/{}.csv'.format(ticker))else:print('Already have {}'.format(ticker))get_data_from_yahoo()

and it crashes with a few erros, not just one. The first error is that I should override pandas data reader.

DeprecationWarning: 
Auto-overriding of pandas_datareader's get_data_yahoo() is deprecated and will be removed in future versions.
Use pdr_override() to explicitly override it.
DeprecationWarning)  

How do I override it? I really don't know how to, I am new to Python - sorry for being a noob.

Then we have this:

    get_data_from_yahoo()File "C:\Users\Mehdi\Desktop\Python finance\SP500_List.py", line 36, in get_data_from_yahootickers = pickle.load(f)

I really dont understand why this happens, because I have checked my code with the Youtuber and they match. So some pointer would be appriciated.

Finally, I have this error:

  EOFError: Ran out of input

which I also don't know what it means.

To add to that, I have installed the 'fix_yahoo_finance' package and tried that with the new code as well and it still does not work.

Any help is appriciated. Thanks :)

You have two mistakes in your code:

1. In line 22 in function save_sp500_tickers(), instead of this:

   with open("sp500tickers.pickle", "wb") as f:pickle.dump(ticker, f)
   

   it should be:

   with open("sp500tickers.pickle", "wb") as f:pickle.dump(tickers, f)
   

   So it is tickers instead of ticker

2. In line 47 in function get_data_from_yahoo(), instead of this:

   if not os.path.exists('stock_dfs/{}.csv'.format(ticker)):data = pdr.get_data_yahoo(ticker, start, end)df.to_csv('stock_dfs/{}.csv'.format(ticker))
   

   It should be:

   if not os.path.exists('stock_dfs/{}.csv'.format(ticker)):data = pdr.get_data_yahoo(ticker, start, end)data.to_csv('stock_dfs/{}.csv'.format(ticker))
   

   You need to use data instead of df (in video was used df = web.DataReader(ticker, 'yahoo', start, end) which you change in data = pdr.get_data_yahoo(ticker, start, end) but you forgot to change df.to_csv('stock_dfs/{}.csv'.format(ticker)) to data.to_csv('stock_dfs/{}.csv'.format(ticker)))
