This is one of the reasons why address reuse is discouraged: once you redeem a UTXO, you reveal your public key, which is slightly more sensitive than your bitcoin address history. We do this passing a valid bitcoin address to function history. from bitcoin import * print(history(a_vaid_bitcoin_address)) If you don't have an address, you can look one up from Blockchain.
