[issue32005] mutliprocessing.Array misleading error message in slice assignment

[Steven D'Aprano]

New submission from Steven D'Aprano <steve+python at pearwood.info>:

multiprocessing.Array slice assignment claims to require a single character even if it requires more than one:

py> arr = multiprocessing.Array('c', 3)
py> arr[:] = b'xyz'  # works
py> arr[:] = 'xyz'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.5/multiprocessing/sharedctypes.py", line 226, in __setitem__
    self._obj[i] = value
TypeError: one character bytes, bytearray or integer expected
