Re: Noobie: Open file -> read characters & multiply

Thanks to all that responded. I chose a modified version of Scott's second recommendation: time = line[:8] decoded_File.write( '%00.4f' % (int(time, 16) * .0001) + ', ') 'print >>' added a CRLF that I didn't need, so I went with '.print' (I need to process about 20 values from the remaining bytes
