WebJun 25, 2008 · With this in hand, you are ready to write Python code. First, make sure you open the file in binary mode: binaryFile = open ("Measurement_4.bin", mode='rb') Now you can use the file.read (n) command to read n bytes of data from the file. This data is read as a string, so you will need the struct module to interpret the string as packed binary data. WebbinaryFile = open ('Measurement_4.bin', mode='rb') (data.offset,) = struct.unpack ('>d', binaryFile.read (8)) Note that mode is set to 'rb' for binary. With numpy you can directly do this as data = numpy.fromfile ('Measurement_4.bin', dtype='>d')
