Re: TypeError: 'bytes' object is not callable error while trying to converting to bytes.
You have assigned a bytes value to the name bytes:
>>> bytes([10, 20, 30, 40])
b'\n\x14\x1e('
>>> bytes = bytes([10, 20, 30, 40])
>>> bytes([10, 20, 30, 40])
Traceback (most recent call last):
File "", line 1, in
TypeError: 'bytes' object is not callable
bytes is now bound to the value b'\n\x14\x1e(', which is not callable. This
global is shadowing the built-in. Delete it:
del bytes

Until python4 introduces the 'data' built in. :) Python 3.6 could introduce that, no need to wait for Python 4. :) However, it wouldn't be critical to this code, unless the builtin's meaning is also wanted; it'd be on par with the shadowing of 'file' earlier - given how rarely Python programs actually need 'file' (rather than 'open'), it's not a big deal to shadow that one.

Here you re-bind the name ‘file’ to the return value from that call.
bytes = file.read()
Here you re-bind the name ‘bytes’ to the return value from that call.
records = [bytes([char] * 8) for char in b'spam']
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.
