Special methods for sequence types

__getslice__(self, i, j)

Called to implement evaluation of self[i:j]. Note that missing i or j are replaced by 0 or len(self), respectively, and len(self) has been added (once) to originally negative i or j by the time this function is called (unlike for __getitem__).

__setslice__(self, i, j, sequence)

Called to implement assignment to self[i:j]. Same notes as for __getslice__.

__delslice__(self, i, j)

Called to implement deletion of self[i:j]. Same notes as for __getslice__.
