x = getattr(self, source) will work just perfectly if source names ANY attribute of self, including the other_data in your example.

How to Access an Object Attribute Given the Attribute Name as a String? – Be on the Right Side of Change
You may know the following problem: You have an object’s attribute name as a string—say, you’ve read it from a file—and you want to access the attribute with the given name. But you cannot use the syntax object."attribute" because the dot notation only allows for name-access like this: object.attribute. How do you resolve this problem? This article will show you how! Quick Solution: There are four ways to access the object attribute in Python via the built-in functions:

Attributes represent the properties or characteristics of an object, while methods define the actions or behaviors that an object can perform.

When inheriting from a class without __slots__, the __dict__ and __weakref__ attribute of the instances will always be accessible.

r/learnpython on Reddit: addressing class attribute with a variable?
February 14, 2025 -
Is there a possibility to dynamically call class attributes based on variables?
example:
I have a class example, that has two attributes: first and second.
So you could define something like
test = example("foo", "bar") and you'd have test.first == "foo" and test.second == "bar".
Then I have another variable, say place, which is a string and is either place = "first" or place = "second".
Can I somehow call test.place?
There are a bazillion other uses for this, but at this current moment I'm trying to write a small "app" that has a few display strings, and I want to be able to select from two strings to display (two languages) based on command line argument.

What are you actually trying to do? I can't really work out what you're asking. If this is for language selection can't you store all the text you may need to display in a dictionary with the keys being the language code and access it through that?

r/Unity3D on Reddit: How to get and set variable of a class instance using string (like getattr/setattr functions in Python)
December 6, 2023 -
Hi,
I am looking for a function in C#/Unity which allows me to get or set a variable of an instance using a string that is the same as the variable’s name.
I was using Python until recently, which does have such a function, so I want to demonstrate what I mean using that:
Let’s assume we have class called “Human”, and an instance of that class, “John”.
The class “Human” has a variable called “speed”, and “speed” variable of “John” is, for example, 10.
In Python, you can access the value ‘10’ by doing this:
getattr(John, "speed") #this would return the same value as John.speed, which is 10
Also you could set that variable to another value, like:
setattr(John, "speed", 5) #after this, John.speed or getattr(John, "speed") would return 5.
Is there a way to do this in C#/Unity?
I’m new to Unity, so although I tried to find the answer in the internet, I couldn’t find one. Can you help me?
Thanks.

The keyword you're looking for is "reflection". Never personally used it, but that's what you wanna look into. Although I believe it is not a recommended way of doing things.

Why would you ever want to use strings, they suck. If you don't want to make fields public, use c# properties with public getter or just write a public get method, same thing. There is also a thing called SerializedObject in unity, and there you can access the class field with FindProperty method. And you can pass nameof(Human.speed) argument instead of a string. But it works only on the classes that are of Unity.Object type if I'm not mistaken, so it works only on mono behaviours, scriptable objects, etc

Accessing Object Attributes in a Python Class Using Format - Andrea Minini
In lines 4 and 5, I create two instances of the Capital class, named Italy and France. Each instance is assigned the name of the respective capital city. To retrieve the value of the city attribute for the Italy object, you can write: print("The capital of Italy is {Capital.city}".format(Capital=Italy)) Within the string, the placeholder refers to the attribute Capital.city. The format() function tells Python which object to use (Italy in this case).

After reading rejected Syntax For Dynamic Attribute Access I'm using a mixin class providing dictionary-style access to an object's attributes :
class MyClass:
def __init__(self):
self.name = None
self.text = None
def __getitem__(self, name):
return getattr(self, name)
def __setitem__(self, name, value):
return setattr(self, name, value)
def __delitem__(self, name):
return delattr(self, name)
def __contains__(self, name):
return hasattr(self, name)
While still being able to set attributes directly:
myclass = MyClass()
myclass.name = "foo"
myclass.text = "bar"
it's then possible to set them dynamically :
for attr in ('name', 'text'):
myclass[attr] = confirm(attr, default=myclass[attr])

They can be accessed using the class name and through an instance of the class. Class attributes are defined outside of any method, including the init method, and are typically assigned a value directly.
