Other strange thing is that the `raise` statement doesn't require to instantiate an Exception object, allowing to pass an Exception class to it.

Is there any difference between this two lines of code?
Questions like this below on python-list, not here.
The main difference (I *think* this is still true) is that in the first example, if the exception is caught in C it can avoid instantiation.
The the second form allows addition of a message, which is usually a good idea. -- Terry Jan Reedy
