I am trying to access yahoo finance from a web app and I am getting this ValueError. I see that yahoo.com is whitelisted on my free account. Do I need to add a special call somewhere in one of my source files if I am trying to call an external site? This program works fine when I run it from my local computer, address is : stock.pythonanywhere.com/status/ and the error pops up when I hit the update quote button. Thanks for any pointers you might have!

ValueError: read of closed file
What does the update do? ie. what is the call to access yahoo.com?

The update button from the html calls a function that pulls data using the YahooFinancials app, https://pypi.org/project/yahoofinancials/
the code is like this:
from yahoofinancials import YahooFinancials as yf
def update_quote(self, symbol):
pull_data = yf(symbol)
sym = pull_data.get_stock_price_data(reformat=True)
current_price = sym[symbol]['regularMarketPrice']
return current_price
This code works when I run it standalone and also within my django app when I run it on the local server. The problem I am getting is when I run it uploaded to the pythonanywhere site.
Where are you seeing the error message? Is it in the error log? If so, could you post the full traceback?
