reading individual bytes of multiple binary files using the Python module fileinput

I can read the first byte of a binary file like this:

with open(my_binary_file,'rb') as f:
    f.read(1)

But how do I do this with the module fileinput? If I run this code:

import fileinput
with fileinput.FileInput(my_binary_file,'rb') as f:
    f.read(1)

then I get this error:

AttributeError: 'FileInput' object has no attribute 'read'

Is there a module similar to fileinput, which allows me to read bytes/characters of multiple binary files instead of lines?

EDIT: Reading a line of the binary file and looping over it is not an option, as the binary file is large and contains no line breaks.

This is not the solution I was after, but this is the solution I ended up with:

def process_binary_files(list_of_binary_files):

    for file in list_of_binary_files:
        with open(file,'rb') as f:
            yield f.read(1)

    return

list_of_binary_files = ['f1', 'f2']
generate_byte = process_binary_files(list_of_binary_files)
byte = next(generate_byte)
