[Python-Dev] slice subscripts for sequences and mappings (original) (raw)

This doesn't align well with the documentation, in at least two places.

Another place is in http://docs.python.org/dev/reference/datamodel.html:

" object.getitem(self, key)

Called to implement evaluation of self[key]. For sequence types,

the accepted keys should be integers and slice objects. [...] "

Once again, at the C API level this isn't accurate since only integer keys are handled by the sequence protocol, leaving slice keys to the mapping protocol.

The datamodel doc should stay as it is, because it's correct for Python-written classes. But the relevant C API sections really need some clarification.
