彩票主网分叉测试问题

Question

我一直在免费代码营学习Solidity 16小时课程。我一整天都在测试中遇到问题。我本来可以通过，但现在我被卡住了。我在主网fork上测试时的错误与Patrick Collins类似，但一旦纠正，我就出现了一个巨大的错误。下面是我的代码以及巨大的错误。

您必须正确缩进python代码才能使其工作。

def test_get_entrance_fee():
account = accounts[0]
lottery = Lottery.deploy(
config["networks"][network.show_active()]["eth_usd_price_feed"],
{"from": account},
)

Python'；s对缩进的制表符和空格的解释
