I'm new to Python and can't readily find the appropriate function for the following situation:
I'm reading in a byte stream from a serial port (which I've got working OK with pyserial) and which contains numeric data in a packed binary format. Much of the data content occurs as integers encoded as 2 consecutive bytes, ie a 2-byte integer. I'm guess that there should be a function available whereby I can say something like: My2ByteInt = ConvertToInt(ByteStream[12:13]) to take a random example of the 2 bytes occurring at positions 12 and 13 in the byte stream. Can anyone point me in the right direction towards a suitable function please? NB I don't know without further checking exactly how the bytes are encoded, but I'm just transcribing some code across from a Windows VB.Net program and these same bytes could be read straight into a standard 2-byte signed short int, so I can be confident that it's a fairly standard Windows-compatible encoding. -- http://mail.python.org/mailman/listinfo/python-list
