SyntaxError: invalid syntax ??

[korenron]

Hello ,
starnge problem
I have a working python code that print me canbus data
today I enter the code to a new machine and I get this error (just copied the code)

def ReadCanBusData():
    bus = can.interface.Bus(channel='can0', bustype='socketcan')
    while True:
        try:
            message = bus.recv(10)
        except Exception as e:
            print('error in CanBus!')
        else:
            if message is None:
                print('TimeOut!')
            else:
                TS = datetime.datetime.now()
                pid_temp = message.arbitration_id
                pid_int = int(pid_temp)
                data_byte = message.data
                try:
                    data_temp = [f"{byte:02x}" for byte in data_byte]
                except Exception as e:
                    print(e)
                Data = ' '.join(data_temp)
                PID = f"{pid_int:08X}"
                PID = PID.upper()
                print(str(TS) + ": " + PID + ": " + Data)

when I try to run it I get :

 python3 ReadCanbus.py
  File "ReadCanbus.py", line 39
    data_temp = [f"{byte:02x}" for byte in data_byte]
                             ^
SyntaxError: invalid syntax

and also this (when I disable line 39,40):

 python3 ReadCanbus.py
  File "ReadCanbus.py", line 41
    PID = f"{pid_int:08X}"
                         ^
SyntaxError: invalid syntax

again - it's the same file running on other machine

waht is this , and what is wrong?
Thanks ,
