我需要帮助。我想每3秒轮换一次FIT代币流动性余额，但我需要一些帮助

contract = web3.eth.contract(address=address , abi=abi)
print(contract.functions.name().call())
balance = contract.functions.balanceOf('0x5e8ce185475855E60fA121389331cd6cEd61ea57').call()
print(web3.fromWei(balance, 'ether'))
我得到了最新的信息。但是我想要每3秒更新一次信息。
Ba = balance
while Ba > 0:
if Ba > 0:
print(web3.fromWei(balance, 'ether'))
time.sleep(3)
else:
print('0')
但这打印我一个结果多次:(
您需要每次使用.call()来刷新余额!
balance = contract.functions.balanceOf('0x5e8ce185475855E60fA121389331cd6cEd61ea57')
while True:
print(web3.fromWei(balance.call(), 'ether'))
time.sleep(3)
