[New-bugs-announce] [issue18690] memoryview not considered a sequence

Simon Feltman report at bugs.python.org
Thu Aug 8 22:38:26 CEST 2013

New submission from Simon Feltman:

This was a bit unexpected as memoryviews support all the methods of the Sequence abstract base class:

>>> import collections
>>> b = bytearray(b'asdf')
>>> isinstance(b, collections.Sequence)
>>> m = memoryview(b)
>>> isinstance(m, collections.Sequence)

It would be nice if memoryview was registered with the Sequence ABC and MutableSequence for writeable memoryviews.
