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> Find a line of text in another file (Python) 2012-06-15T15:45:18-07:00sami janhttp://code.activestate.com/recipes/users/4064232/http://code.activestate.com/recipes/578164-find-a-line-of-text-in-another-file/ <p style="color: grey"> Python recipe 578164 by <a href="/recipes/users/4064232/">sami jan</a> (<a href="/recipes/tags/line/">line</a>, <a href="/recipes/tags/search/">search</a>).

Revision 6. </p> <p>The script it self is very self explaining - the task is simple. *NIX only unless with cygwin perhaps?</p> <p>To start this open a terminal and strike the "Tab" key to get all possibilities (strike y, and strike the space key alot). Select all then Copy and save in "comms.txt" Modify the file so ONLY the possiblities consume a line; no prompts or extra newlines.
