    The mybytes argument must either support the buffer protocol or be an

97
    built-in objects that support the buffer protocol.
98
    The byteorder argument determines the byte order used to represent the
99
    integer.  If byteorder is 'big', the most significant byte is at the
100
    beginning of the byte array.  If byteorder is 'little', the most
101
    significant byte is at the end of the byte array.  To request the
102
    native byte order of the host system, use `sys.byteorder' as the byte
103
    order value.

    The signed keyword-only argument indicates whether two's complement is
105
