What I meant was the exact format of a given string. Could you write what is the output of print(data)?

my current output is this: data = str(int ser.serial_readline(), 16) because the arduino converts an int before it sends it, I need to convert it back to an int to compare the 2 sets of data

@Kuba the arduino sends a number convets to hex, and sends via usb. the script stores it as an integer, ie the numbers are not the same as script is displaying hexadecimal numbers. I would like to convert it back to an integer so I can compare notes. from what I can see is that the script reads the serial, and puts it in a string, here is the fetching code. data = str(int ser.serial_readline(), 16) so if I change the int to hex it does not communicate, what I can see is that the number becomes an integer and displayed in a string, but the current integer is set to the converted hex number, now I would like to convert it back to the original integer.
