HackUnderway/BlockChain ? reverse-engineered prompt

Build me a simple Python app that lets me check Bitcoin wallet activity from an address. I want to paste in a wallet address and see the total number of transactions, how much Bitcoin was received, how much was sent, and the current balance in a clean, easy to read output. If it helps, make it work as a small command line tool first, with a friendly prompt and clear results.

Please include whatever setup files are needed so I can install the requirements and run it with one command. If you need current API or library details, look them up online and use the latest working approach. Make the interface feel polished and make sure it handles invalid or empty addresses without crashing.
