代码如下：

import json
from web3 import Web3

# 使用Infura作为节点提供商
infura_url = "https://mainnet.infura.io/v3/YOUR-PROJECT-ID"
w3 = Web3(Web3.HTTPProvider(infura_url))

# Uniswap V3 Multicall 合约地址
multicall_address = "0x1F98415757620B543A52E61c46B32eB19261F984"

# Uniswap V3 池合约地址列表
pool_addresses = [
    "0x8ad599c3A0ff1De082011EFDDc58f1908eb6e6D8",
    "0xc2e9f25be6257c210d7adf0d4cd6e3e881ba25f8",
]

# Uniswap V3 池 ABI
with open("path/to/uniswap_v3_pool_abi.json") as f:
    pool_abi = json.load(f)

# 准备 Multicall 数据
calls = []
slot0_function_signature = "slot0()"
for pool_address in pool_addresses:
    calls.append((pool_address, Web3.sha3(text=slot0_function_signature)[:10].hex()))

# Uniswap V3 Multicall 合约 ABI
with open("path/to/uniswap_v3_multicall_abi.json") as f:
    multicall_abi = json.load(f)

# 创建 Multicall 合约实例
multicall_contract = w3.et
