What do you use as symbols for Python ?

When you need some symbols in your program, what do you use in Python ? For example, an object get a state. This state is more readable if expressed as a symbols, for example "opened", "closed", "error". Typically, in C or C++, I would use an enum for that: enum OBJECT_STATE { opened, closed, er
