annual_income = res[year, INCOME_COL] TypeError: 'float' object is not subscriptable

这个错误提示的意思是，你在尝试从`res`这个变量中通过索引来获取特定年份(`year`)的'income'列(INCOME_COL)，但是`res`不是一个可以按索引访问的数据结构，比如列表、字典或者是Pandas DataFrame。`annual_income = res[year, INCOME_COL]`这行代码试图像操作数组一样对一个浮点数(`float')对象进行切片，这是不允许的。

解决这个问题，你需要确认`res`是否是一个包含所需数据的DataFrame，并且`year`是它的行标签，`INCOME_COL`是列名。如果你想要按照年份筛选收入数据，你应该做类似这样的操作：

if isinstance(res, pd.DataFrame):  # 检查是否是Pandas DataFrame
    if year in res.index:  # 确保年份在索引集中
        annual_income = res.loc[year, INCOME_COL]
    else:
        print(f"Year {year} not found.")
else:
    raise TypeError("res must be a pandas DataFrame.")

next_state = self.states[index] TypeError: 'float' object is not subscriptable

这个错误通常是由于将 float 类型的变量视为数组或对象进行索引引起的。出现此错误的原因可能是您的代码中有一个变量被分配了不正确的值，或者可能是您在使用该变量之前没有对其进行类型检查或转换。

您可以检查代码中的变量类型并确保它们都是正确的。您也可以尝试在使用 float 类型的变量之前，确保其值不是 None 或其他非预期的值。

zip TypeError: float object is not iterable

This error occurs when you try to iterate over a float object using a loop. A float is a numeric data type in Python that represents a decimal number. However, you cannot iterate over a float as it is not an iterable object.

For example, suppose you have a float value and you try to iterate over it using a for loop:

my_float = 3.14

for num in my_float:
    print(num)

This code will result in a TypeError because you cannot iterate over a float.

To fix this error, you need to ensure that you are iterating over an iterable object, such as a list or a tuple. If you need to convert a float to an iterable object, you can do so by wrapping it in a list or tuple:

my_float = 3.14

my_list = [my_float]

for num in my_list:
    print(num)

This code will iterate over the list containing the float value, rather than the float itself.
