So I am using this public program to parse this byte data, but I am getting the error that the "bytes" object I am parsing has no attribute 'encode' what is going on and how to I fix it?

     62         for j in range(4):

     63             b = f.read(1)

---> 64             b = b.encode('hex').upper()

     65             tmpHex = b + tmpHex

     66         tmpHex = ''



AttributeError: 'bytes' object has no attribute 'encode'

I have tried to replace encode with something else but I end up getting another error which is on line 65 above saying that b and tmpHex cannot be concatenated. How do I solve this?

I could not include all the code because stackoverflow said I had too much code and too little writing.

I had to reduce the code because I had too much code and not enough details.
