/* Type PyByteArrayObject represents a mutable array of bytes.
 * The Python API is that of a sequence;
 * the bytes are mapped to ints in [0, 256).
 * Bytes are not characters; they may be used to encode characters.
 * The only way to go between bytes and str/unicode is via encoding
 * and decoding.
 * For the convenience of C programmers, the bytes type is considered
 * to contain a char pointer, not an unsigned char pointer.
