Class attributes are useful in some cases such as storing class constants, tracking data across all instances, and defining default values. 1) Storing class constants. Since a constant doesn’t change from instance to instance of a class, it’s handy to store it as a class attribute. Put most code into a function or class.

However, there is no base class called "name", so it fails. Instead, all you need to do is have the variable in the special __init__ method, which will mean that the class takes it as a variable.The closest equivalent to Java's toString is to implement __str__ for your class. Put this in your class definition: def __str__(self): return "foo". You may also want to implement __repr__ to aid in debugging.
