I suppose he thinks that hexadecimal and binary is the same. The data you showed is binary. For example the following sequence of bytes 9 1 120 1 253 2 is displayed as the bytestring b'\t\x01x\x01\xfd' in Python. When the bytes are shown as hexadecimal numbers the same data looks like this: 09 01 78 01 fd 02 >> If you can control what data is generated then using text would indeed >> simplify things. > > using text mean strings?

I assume that means Open Sound Control... _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
