How to dynamically set column value in flask_sqlalchemy

Question

I have a route which may take in a variating number of request parameters. For example, I have an array of possible params which MAY be present in my data dictionary:

possible_params = ["param_1", "param_2"...]

All of the parameters in the possible_params array are columns in a db.Model instance (table). Lets call the table Users.

What I want to do is basically loop through each parameter, check if it exists in the data dictionary and set the attribute of Users instance accordingly.

That is what puzzles me - how do I set the value of a class instance attribute when the name of that attribute is a variable?

I could go with the traditional approach of

if "param_1" in data:
    Users.param_1 = data["param_1"]
if "param_2" in data:
    Users.param_2 = data["param_2"]

but that seems a little... caveman-ish.
