New submission from Vincent Pelletier: Quoting a github gist[1] (not mine, I found it while googling for this error) clearly illustrating the issue:
# Python 2 >>> b = bytearray(8) >>> v = memoryview(b) >>> v[0] = 42 Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: 'int' does not have the buffer interface >>> b bytearray(b'\x00\x00\x00\x00\x00\x00\x00\x00') # Python 3 >>> b = bytearray(8) >>> v = memoryview(b) >>> v[0] = 42 >>> b bytearray(b'*\x00\x00\x00\x00\x00\x00\x00') This is especially annoying as on python3 bytearray.__setitem__ only accepts integers, making working py2 code totally incompatible with py3 in a 2to3-undetectable way.
