<p style="color: grey"> Python recipe 134892 by <a href="/recipes/users/98032/">Danny Yoo</a> (<a href="/recipes/tags/sysadmin/">sysadmin</a>). Revision 2. </p> <p>A small utility class to read single characters from standard input, on both Windows and UNIX systems. It provides a getch() function-like instance.</p>

<p style="color: grey"> Python recipe 66521 by <a href="/recipes/users/98032/">Danny Yoo</a> . </p> <p>A utility class that makes writing callbacks more pleasant than using lambda. Especially using with Tkinter.</p>

<p style="color: grey"> Python recipe 197530 by <a href="/recipes/users/98032/">Danny Yoo</a> (<a href="/recipes/tags/algorithms/">algorithms</a>). Revision 2. </p> <p>Provides a mergeiter() function that can merge two iterators into a single iterator. Uses generators, and guarantees constant memory use.</p>

<p style="color: grey"> Python recipe 105962 by <a href="/recipes/users/98032/">Danny Yoo</a> (<a href="/recipes/tags/algorithms/">algorithms</a>). </p> <p>permIter() takes a sequence and returns an iterator that goes through all possible permutations of that sequence.</p>

<p style="color: grey"> Python recipe 498261 by <a href="/recipes/users/98032/">Danny Yoo</a> (<a href="/recipes/tags/text/">text</a>). Revision 3. </p> <p>The str() in the standard library behaves in a slightly weird way when applied against lists: on each element of the list, the repr() is appended. In contrast, this module provides a deep_str() that deeply applies str() across lists.</p>

<p style="color: grey"> Python recipe 52271 by <a href="/recipes/users/98032/">Danny Yoo</a> (<a href="/recipes/tags/algorithms/">algorithms</a>). </p> <p>This piece of code takes in two infinite sequences, and, with the help of a cute math function, can cross these two together into another infinite sequence. (This is related to the diagonalization proof that the rationals are countable.) It should guarantee that, given enough time, we can reach any particular element.</p>

<p style="color: grey"> Python recipe 161816 by <a href="/recipes/users/98032/">Danny Yoo</a> . </p> <p>This extension to xmlrpclib allows us to maintain a session with a JSP server, so that there appears to be a stateful session. It tries to maintain the JSESSIONID call between calls to the server.</p>
