Classes allow us to encapsulate multiple data attributes in a single object.

class Person:
  name = "default name"
  age = 0

The code above defines a class Person. The class has two data attributes name and age. The values of these attributes default to "New person" and 0.

p = Person()
print(p.name) # default name
p.name = "Harald"
print(p.name) # Harald

An object of class Person is created with parentheses and assigned to the variable p. The name of the person is overwritten with Harald. This is done using object access notation with a dot: p.name.
