hi guys, is there a way to get the TotalIssuance value at a given era or block number/hash ?

For a certain block hash you can use:

total_issuance = substrate.query("Balances", "TotalIssuance", block_hash="0x11a4a00cfb10aa94884afc79d31b34bb212017449748a7a130d8015108a55cb4")
print(total_issuance.value)

This will work for all storage functions, to query the state at the time of the block hash.
