Use a.empty, a.bool(), a.item(), a.any() or a.all().

在你的代码中，出现了相同的错误。这是因为在计算aqi时，你尝试将Series对象（iaqi1和iaqi2）与标量值进行比较，导致了"The truth value of a Series is ambiguous"错误。

要解决这个问题，你需要使用逐元素的比较运算符来比较Series对象中的每个元素。在这种情况下，你可以使用Series对象的.max()方法来找到iaqi1和iaqi2中的最大值。

请修改以下代码：

aqi = max(iaqi1, iaqi2)

为：

aqi = pd.Series([iaqi1, iaqi2]).max()

这样就可以避免出现"The truth value of a Series is ambiguous"错误，并找到iaqi1和iaqi2中的最大值作为aqi。请确保在使用该代码之前导入pandas库（import pandas as pd）以使用pd.Series()方法。
