Google Model Attribute get by name

Question

Can I get a google model attribute by passing a string to some function?

To illustrate:
If I were to do .properties().keys(), it would return all the attributes as a list of strings.
If 'Person' is a model and 'age' is an attribute of person, I would like to do something like this:

Person.properties()['age'] = 25

where I set the person's age to 25

Answer 1

Use Python's setattr:

setattr(a_person, 'age', 25)
