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. | |
