Django access to model Properties Dynamically

I'm very new to Django so this question might be very basic.

I have a model called UserScores, which contains 16 different score properties, each representing a user score based on the game he/she has played.

when a user plays a game and finish it, the score he gets in that game should be added to the related property in his/her UserScores object. so the code looks like this:

if game_name == "game_1":
  self.game1_score += score
elif game_name == "game_2":
  self.game2_score += score
...

in php I used to run a code like this:

obj.{game_name} += score

so no matter what the game name was, the correct property was edited,

Now my question is that,

Is there a dynamic way to access properties on a Django model objects?

You can use getattr/setattr to achieve what you want. For example, to set the field value:

old_value = getattr(obj, field_name)
setattr(obj, field_name, old_value + score)
