You can define instance variables when instantiating a class.
class Person:
def __init__(self, first_name, last_name):
self.first_name = first_name
self.last_name = last_name
def full_name(self):
return self.first_name + " " + self.last_name
Then those instance variables can be accessed as properties of that class instances.
me = Person("Josh", "Branchaud")
print(me.first_name) #=> "Josh"
print(me.full_name()) #=> "Josh Branchaud"
