Any disadvantages or advantages of using multiple classes under one file name? For example:

class Monster:
  hit_points = 1
  color = 'yellow'
  weapon = 'sword'

class Hero:
  hit_points = 0.5
  color = 'white'
  weapon = 'axe'

I would say it is dependent on how complex your code/application is becoming.

Advantages

Code is in one place, easy to import

Disadvantage

No separation of concerns Less organized classes

In frameworks like Django that use models. You do see multiple classes listed within one model.py* file but they are still related concerns. So if the **models.py for particular App called lets say "Movies"

You might have multiple classes structure like so:

class Actor:
    pass

class Genre:
    pass

class Movie:
    pass

But inside this "module" called Movies these are all classes that relate to a Movie. So its perfectly normal to see this.
