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