4. Then the contract destroy

backup from web3 import Web3

Connect to your Ethereum node (replace 'your_node_url' with your actual node URL)

w3 = Web3(Web3.HTTPProvider('your_node_url'))

Replace 'contract_address' with the actual address of your smart contract

contract_address = '0xYourContractAddress'

Replace 'your_private_key' with the private key of your Ethereum account

private_key = '0xYourPrivateKey'

Replace 'your_contract_abi' with the ABI of your smart contract

contract_abi = [ { "constant": True, "inputs": [], "name": "getRemainingTime", "outputs": [{"name": "", "type": "uint256"}], "payable": False, "stateMutability": "view", "type": "function", } ]

Create a contract instance

contract = w3.eth.contract(address=contract_address, abi=contract_abi)

Replace 'your_account_address' with the address of your Ethereum account

account_address = '0xYourAccountAddress'

Build the transaction

transaction = contract.functions.getRemainingTime().buildTransaction({ 'from': account_address, 'gas': 200000, 'gasPrice': w3.toWei('50', 'gwei'), # Replace '50' with your desired gas price in gwei 'nonce': w3.eth.getTransactionCount(account_address), })

Sign the transaction

signed_transaction = w3.eth.account.sign_transaction(transaction, private_key)

Call the contract function using eth_call

result = w3.eth.call({ 'to': contract_address, 'data': signed_transaction.rawTransaction })

Decode the result

remaining_time = int(result, 16) print(f'Remaining Time: {remaining_time} seconds')
