bytearray, type and format confusion



  • Hello, I could really use a hint here as to understand the type bytearray which I'm using for sending to a java socket on an rpi.

    In REPL console I typed this:

    data = bytearray()
    print(data)
    **bytearray(b'')**
    data.append(40000)
    print(data)
    **bytearray(b'@')**
    print(data, encoding='utf8')
    **bytearray(b'@')**
    

    What format is this? How come that the int 40000 is shown as '@' ?? It's not hexadecimal and it's not a byte (0-255), but obviously there's something I don't get..



  • @soren Add ``` alone on the lines before and after your code, or prefix them all with 4 spaces to have them formatted as code.

    40000 % 256 (or 40000 & 255, i.e. keeping the 8 least significant bits) = 64, which is the code point for @.
