Simple Byte Question

[malonn]

Thanks for the help, @buran. This forum has been most helpful to me.

Well I finally figured out the problem.

def get_ebml_id(file):
    byte = file.read(1)
    dec = ord(byte)
    if dec & 0b10000000: #1 byte long EBML ID
        return byte
    elif dec & 0b01000000: #2 bytes long EBML ID
        return struct.unpack('>H', byte + file.read(1))[0]
    elif dec & 0b00100000: #3 bytes long EBML ID
        return struct.unpack('>L', b'\0' + byte + file.read(2))[0]
    elif dec & 0b00010000: #4 bytes long EBML ID
        return struct.unpack('>L', byte + file.read(3))[0]

If the byte read is supposed to be one byte long, it returns a byte object. It was throwing off an otherwise correct script. So, I changed

if dec & 0b10000000: #1 byte long EBML ID
        return byte

...to

if dec & 0b10000000:  # 1 byte long EBML ID
        return int.from_bytes(byte, byteorder='big')

...and all works as expected. I have learned that bytes objects are definitely not integers.
