Need to Create Class with Default Values for Attributes

Question

I need to create a class that that stores tax data as default values, but that can be populated with actual data from tax returns. So for instance, let's say I have three categories: income, statutory adjustments, and tax computation, each which contains several attributes. Ideally, I would like to have three self arguments that I can pass around to parts of a tax calculator. But I would want to be able to pass around each attribute in the self string individually. Right now I have this:

class taxReturn:

    def __init__(self): 

        self.income = [attribute1, attribute2, attribute3]
        self.statut = [attribute4, attribute5, attribute6]
        self.tax_comp = [attribute7, attribute8, attribute9]

Each attribute would have to be set to a default value that could be passed around, but then later filled in with actual data.

Any help would be appreciated. Thanks!

Answer 1

Why not just define this in the __init__ method?

class taxReturn:

    def __init__(self, income = [attribute1, attribute2, attribute3],statut = [attribute4, attribute5, attribute6],tax_comp = [attribute7, attribute8, attribute9]): 

        self.income = income
        self.statut = statut
        self.tax_comp = tax_comp

# To create instance of taxReturn:

txR = taxReturn() # income, statut and tax_comp will take the default values defined bellow

//OR

txR = taxReturn(income = NewListOfAttribute1, statut=NewListOfAttribute2,tax_comp=NewListOfAttribute3) # income, statut and tax_comp will take the new attribute defined
