在使用 web3 在 python 中完成交易后，我试图获取交易的哈希和数据。我有以下代码：

nonce = web3.eth.getTransactionCount(account)
tx = {
    'nonce' : nonce,
    'gas' : 5000000,
    'gasPrice' : web3.toWei(50,'gwei'),
    'chainId': 3
}
contract = web3.eth.contract(address=address, abi=abi)
tx_hash = contract.functions.savetr(Addressmapping,Coordenadas,imh,Url).buildTransaction(tx)
signed_tx = web3.eth.account.signTransaction(tx_hash, private_key)
web3.eth.sendRawTransaction(signed_tx.rawTransaction)
tx_receipt = web3.eth.waitForTransactionReceipt(signed_tx)
print(tx_receipt)

事务工作正常并成功完成，但使用“signed_tx”提取数据会引发此错误：

我试图将变量传递给字典和其他方法但没有，这是为什么呢？太感谢了！！

     import web3


     tx = { 
       'nonce': nonce, 
        'to': YOUR_ADD,
       'value': web3.toWei(0.01, 'ether'),
       'gas': 21000,
        'gasPrice' : web3.toWei(60, 'gwei'),
      }
       
     

     signed_tx = web3.eth.account.sign_transaction(tx, PRIVATE_KEY) 
     tx_hash = web3.eth.sendRawTransaction(signed_tx.rawTransaction)
     print( "TX hash:" , web3.toHex(tx_hash))

这对你有用吗？
