A classic error in python3. You are concatenating a byte array (rawdata) to a string(data).

Try converting the data to bytes with encoding or do not convert it to string.

Well. If you have 10**6 lines with the structure of:

Then, if the 10**6+1 th line contains a data like:

Then your program will most likely crash.
