Here you re-bind the name ‘file’ to the return value from that call.

Here you attempt to call ‘bytes’, which (as the error says) is not
callable.

You should choose names which are not already bound::

    in_file = open('data.bin', 'rb')
    in_file_content = in_file.read()
    records = [bytes([char] * 8) for char in in_file_content]

When choosing names, try to communicate the *purpose* of the value, its
semantic meaning. The type should be of secondary importance, and almost
always should not be part of the name.
