getRuleID() cannot get the last rule ID

[sdlj2008]

For this example: d.getRuleID()

It can not get the last rule ID because the following code does not contain the index of last rule:

    if len(argv) == 0:
        index = list(range(1, self.getRuleCount()))

The correct code should be as follows:

    if len(argv) == 0:
        index = list(range(1, self.getRuleCount() + 1))
