ascii characters in bytearray instead of hex values

Question

import can

bus = can.Bus(interface='socketcan',
              channel='can0',
              bitrate=500000)

for msg in bus:
    print("{}: {}".format(msg.arbitration_id, msg.data))

As a result of the code above, I get a bytearray with some ascii characters. For example

bytearray(b'@\x1f@\x00\x00\xf4\x00\x00')

bytearray(b'\x00\x90o\x10')

and here below their equivalent.

40 1f 40 00 00 f4 00 00

00 90 6f 10

How can i get pure hex values without "@" and "o" in bytearray?
