Querying full and archive Ethereum nodes with Python

Whenever we need to query data from the blockchain, we fetch it from a node. An archive node differs from a full node since the first holds the entire history of network transactions. Thus, some queries for older block transactions cannot be fetched easily on a full node. In this tutorial, we will programmatically fetch data from the blockchain, switching between full and archive nodes when necessary.
