Reading binary file and looping over each byte

Question

In Python, how do I read in a binary file and loop over each byte of that file?

Answer 1

Here's an example of reading Network endian data using Numpy fromfile addressing @Nirmal comments above:

dtheader= np.dtype([('Start Name','b', (4,)),
                ('Message Type', np.int32, (1,)),
                ('Instance', np.int32, (1,)),
                ('NumItems', np.int32, (1,)),
                ('Length', np.int32, (1,)),
                ('ComplexArray', np.int32, (1,))])
dtheader=dtheader.newbyteorder('>')

headerinfo = np.fromfile(iqfile, dtype=dtheader, count=1)

print(raw['Start Name'])

I hope this helps. The problem is that fromfile doesn't recognize and EOF and allow gracefully breaking out of the loop for files of arbitrary size.
