Python offers very good libraries for data science. By learning 3 or 4 libraries we can do almost all kind of analysis. Yfinance is a great tool that lets us retrieve financial data from Yahoo Finance. With four lines of code, we are able to retrieve 1 year of historical prices from Apple. Pandas make the calculation of moving averages super straightforward. We can also use Pandas to calculate and plot Apple cumulative returns using the pct_change and cumsum methods. This is perfect for comparing how companies are performing relative to others.
