You're overlooking the from_buffer() method. For example:
>>> ba = bytearray(10)
I have an application in which I wanted a fixed-length "array of bytes"
(that's intended as an informal term) where I could read and write
individual bytes and slices, and also pass the array to a DLL (one I
wrote in C) which expects an "unsigned char *" parameter.
I am using ctypes to talk to
