我想获取以太坊数据，所以我使用 geth 和 web3.py。另外，我目前使用 geth light 模式。

我通过下面的代码获取交易数据...

from web3 import Web3
w3 = Web3(Web3.HTTPProvider('http://127.0.0.1:8545'))
block = w3.eth.get_block('latest')
transactions = block.transactions 

for tx in transactions:  
    info = w3.eth.get_transaction(tx)
    print(info)

AttributeDict({'blockHash': HexBytes('0x6e04c6c9151cfa458966d4ec4d10903c2d91558282b51344df64fc2bdae3e0b8'), 'blockNumber': 12875217, 'from': '0x4919F5DA960Edaf34b36473c05a543d4C18Bfc15', 'gas': 155808, 'gasPrice': 23000000000, 'hash': HexBytes('0x4015ec12e9482c668f6470844c5022041a215a59917ad4f2a6973a5688f09ac3'), 'input': '0x7ff36ab50000000000000000000000000000000000000000000068b6f1fa997190b6e8c300000000000000000000000000000000000000000000000000000000000000800000000000000000000000004919f5da960edaf34b36473c05a543d4c18bfc150000000000000000000000000000000000000000000000000000000060f937a80000000000000000000000000000000000000000000000000000000000000002000000000000000000000000c02aaa39b223fe8d0a0e5c4f27ead9083c756cc20000000000000000000000008f8221afbb33998d8584a2b05749ba73c37a938a', 'nonce': 249, 'to': '0x7a250d5630B4cF539739dF2C5dAcb4c659F2488D', 'transactionIndex': 0, 'value': 12000000000000000000, 'type': '0x0', 'v': 38, 'r': HexBytes('0x4475f064437911a03040e68b2ff1dd670f219affad9a20a20e167c873a6743ae'), 's': HexBytes('0x01f7489fe57ed19c3898e57db5a8b18e19c60281b84f9a3b3bdc9991ade0d42b')})

我想接收特定区块中使用的合约信息和账户信息（ex number = 12875255），我该怎么做？

像 ethescan 一样，我想在一个块中读取各种信息。 https://etherscan.io/block/12875255

要获取特定区块编号的区块数据，您可以使用get_block()方法。

例子：

web3.eth.get_block(2000000, true)

第一个参数是块号。第二个参数决定是显示交易细节（true）还是只显示它们的哈希值（false）。
