我一直在 Free Code Camp 16 小时课程中学习 Solidity。我整天都在运行测试时遇到问题。我能够通过，但现在我被卡住了。我在 mainnet-fork 上测试时的错误与 Patrick Collins 类似，但一旦更正，我就遇到了一个巨大的错误。以下是我的代码以及大量错误。

您必须正确缩进您的 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对缩进制表符和空格的解释
