Ever since Yahoo! finance decommissioned their historical data API, many programs that relied on it to stop working.
yfinance aims to solve this problem by offering a reliable, threaded, and Pythonic way to download historical market data from Yahoo! finance.
The library was originally named fix-yahoo-finance, but I’ve since
renamed it to yfinance as I no longer consider it a mere “fix”. For
reasons of backward-compatibility, fix-yahoo-finance now import and
uses yfinance, but you should install and use yfinance directly.
