以结构化方式从python中的函数返回多个值的替代方法？

Question

I'm working on mortgage calculations and many functions calculate multiple different values that I need to return.

For example:

def calculate_something(incomes, debts):
    ...
    return {'value':150000, 'extra':{'dsti_gross':450, 'dsti_supergross':480}}

has many intermediate calculations that are useful in other calculations. These functions are not divisible into smaller functions as it would make the code slower.

I don't want to return tuples as the code might change in the future and I'd need to check all the function calls.

Dictionary is now a way to go but dictionary value calls aren't statically analyzed (most IDEs) so you always need to check the function if you access the correct keys.

Is there another way to work with such returns? Considering classes/objects but every function returns different keys.

要扩展使用类和子类的建议，您可以利用python dataclasses ，它们几乎是为此类问题设计的。
