In simple English
This library lets Python programs talk to the Twelve Data service. You can download historical prices for stocks, currencies, and cryptocurrencies. It also draws charts and calculates technical indicators like moving averages. You need an active API key from the Twelve Data website, which may require a paid plan. The library itself is free to use.
