When we want the same data to be available to every instance of a class we use a class variable. A class variable is a variable that’s the same for every instance of the class.

You can define a class variable by including it in the indented part of your class definition, and you can access all of an object’s class variables with object.variable syntax.

class Musician:
  title = "Rockstar"

drummer = Musician()
print(drummer.title)
# prints "Rockstar"

Above we defined the class Musician, then instantiated drummer to be an object of type Musician. We then printed out the drummer’s .title attribute, which is a class variable that we defined as the string “Rockstar”.

If we defined another musician, like guitarist = Musician() they would have the same .title attribute.
