将同一类的对象放入具有不同键Python的字典中

Question

I have these Objects:

class Object(object):

    def __init__(self, name, *parameters):
        self.name = name
        self.parameters = parameters

    def name(self):
        return self.name

    def parameters(self):
        return self.parameters

class Parameter(object):

    def __init__(self, name, value):
        self.name = name
        self.value = value

My aim is to get all parameters of 1 object in a dictionary, but it needs to end up like this:

{ParameterOne: "ValueOne", ParameterTwo: "ValueTwo"}

Since I have to be able to give the parameters different names, I can't do it like this:

class Parameter(object):

    def __init__(self, value):
        self.ParameterOne = value

I tried it like this which obviously didn't work:

data = {}
    for parameter in object.parameters:
        data.update(vars(parameter))

Is there any way to achieve this?

Answer 1

data = {parameter: ''.join(['Value ', str(index)]) 
         for index, parameter in enumerate(object.parameters)}

This will give you {parameter0: 'Value 0', ...} If you want to get the English words for the numbers, you;ll have to either roll your own function for it or use an external package like inflect .

Just an observation, but most dictionaries would have the string mapping to the object, not the other way around. Is there some reason you're doing it this way?

EDIT:

Rereading your question, are you looking for

data = {parameter: parameter.name for parameter in object.parameters}

I think you might want to try instead

data = {parameter.name: parameter.value for parameter in object.parameters}
