[QUOTE="Tim Roberts, post: 1753374"] Really? This is such a common problem that most Windows Python programmers encounter it very early in their experiments. The issue, of course, is that stdout is opened as a text file, not as a binary file, and we all know that the LF to CR-LF conversion you describe is part of the normal processing of a text file in Windows. If you must send binary data through stdout, do this before you start to write: import os import msvcrt ... msvcrt.setmode( stdout.fileno(), os.O_BINARY ) [/QUOTE]
