"Common base class for all non-exit exceptions."); The only other exceptions that inherit directly from BaseException are GeneratorExit, SystemExit, and KeyboardInterrupt. All the other builtin Exceptions are just regular Python objects that inherit from the built-in BaseException. A Python script can use the raise statement to interrupt execution, causing Python to print a stack trace of the call stack at that point and a representation of the exception instance.

@MaggieYing: Exception is a subclass of BaseException, but it is not the only such subclass. There are other subclasses too, see the inheritance diagram in the docs; those other exceptions are not really errors but signals that you usually would not catch.
