I think what you mean is that, in Python 2, reading from a file returns a byte string regardless of whether you open it in text mode or binary mode. That part is true, but there are other differences between text files and binary files (opened in the correct mode): binary mode is guaranteed to return the actual bytes in the file, but opening it in text mode may perform some platform-specific processing: (1) \r or \r\n may be converted to \n (2) Ctrl-Z may be interpreted as end-of-file There may be other changes made as well. >> ['\x10', '\x20', '\x12', '\x01'] > > If a 'binary' file yields strings, you must be using 2.x. > >> How can I receive this instead? >> [0x10, 0x20, 0x12, 0x01] > > Use python 3.
