So what have you written so far?  Is this a homework assignment and
you've been covering certain parts of Python in a certain order? Is it
part of learning some tutorial?

There are so many ways of accomplishing this sort of thing, that without
some constraints, there are a dozen reasonable responses.  I'll try one:

in the class Player, you make a pair of methods, purchase() and
income(), which manipulate the instance attribute assets.   Then you
make a property that returns the assets.



Class Player:
     ....
     def purchase(self, amount):
        self.assets -= amount
     def income(self, amount):
        self.assets += amount
     def wealth(self):
        return self.assets
