Answer 1

There are two lines of code that have to be inserted to retrieve financials, balance sheet and cashflow statements again.

The solution was found by afju where he/she has posted it in the comments section with a short explanation: https://aroussi.com/post/python-yahoo-finance
so credits to him/her

Here is what you need to change in
.../site-packages/yfinance/base.py
which has worked for me for following version of yfinance:

import yfinance as yf
yf.__version__
>>>'0.1.54'

insert comment in # get fundamentals (around line 375):

#data = utils.get_json(url+'/financials', proxy)

and write these two lines:

url = "{}/{}/financials".format(self._scrape_url, self.ticker)
data = utils.get_json(url, proxy)

so in the end, it looks like this:

# get fundamentals
#data = utils.get_json(url+'/financials', proxy)
url = "{}/{}/financials".format(self._scrape_url, self.ticker)
data = utils.get_json(url, proxy)
