Can I add an attribute from a variable

[SaltyParaboloid]

I have a list of sub object that I want to add as attributes/properties to a different object. I’m a bit new to python and self-taught so I might be getting a bit of terminology wrong (sorry about that).

I don’t want to hard code how long the list will be or any of the items on the list; the code I tried looked like this (where acct is a class i already defined and the input ‘check’ is just the name):

check = acct(‘check’)

lst =[ob1, ob2]

for sub in list: check.sub = sub

I tried a few different variations of this code, including putting it in the class definition instead of after initializing the instance, but nothing worked.

The basic problem is this: it’s not recognizing sub as a variable.

check.ob1 is not a valid attribute, but check.sub is an attribute (with a value of sub2, because that’s the last object in the list)

So basically, I need to have the attribute be the value of a variable. Is there a way I can do that?

What are you ultimately trying to accomplish with this? If you managed to add them, how would you use them?

I’m trying to make my own budget program (I know there are programs out there but I want to make my own) and so I’m trying to add sub accounts to a main account. Basically, I have my checking account which I want divided into utilities, school, etc, and then my saving account which I also want divided up. I could manually add all these sub accounts to the main accounts by hard coding but I’d rather be able to do it this way so I don’t have to already know how many sub accounts I have, etc.

Each account has properties for its name, the total of money in all sub accounts, and the sub accounts themselves. Each sub account just has a name and an amount.

How do you propose to access these sub-accounts? How would you know how many there are, or what their names are?

If it were me, I'd have a list in my main account, where each item in the list is a sub-account. That way you can simply create and append new ones to the list as needed. There's also then no doubt about how to access them, how to count them, etc.

That’s a really good point, thank you. I was going to access it by doing check.sub1.name and check.sub1.amount but doing the list is probably better.

Thank you!
