If there is no input available, it will yield an endless stream of empty strings until input becomes available again; caller is responsible for not going into a busy loop. (Newlines are normalized but not stripped, so if there is actually a blank line in the input, the value yielded will be <code>'\n'</code>.) The intended use case is a thread which must respond promptly to input from a pipe, and also something else which cannot be fed to <code>select</code> (e.g. a <code>queue.Queue</code>). Note that the file object is ignored except for its <code>fileno</code>.</p> <p>Only tested on Unix. Only tested on 3.4; ought to work with any python that has <code>bytearray</code>, <code>locale.getpreferredencoding</code>, and <code>fcntl</code>.</p> "raw_input" For All Versions Of Python...
