<p style="color: grey"> Python recipe 326576 by <a href="/recipes/users/1629020/">Douglas Bagnall</a> (<a href="/recipes/tags/algorithms/">algorithms</a>). Revision 2. </p> <p>The Trigram class can be used to compare blocks of text based on their local structure, which is a good indicator of the language used. It could also be used within a language to discover and compare the characteristic footprints of various registers or authors. As all n-gram implementations should, it has a method to make up nonsense words.</p>

<p style="color: grey"> Python recipe 299058 by <a href="/recipes/users/1629020/">Douglas Bagnall</a> (<a href="/recipes/tags/algorithms/">algorithms</a>). Revision 3. </p> <p>The winnow class uses a heap for finding the best few out of several items. At this it is quicker and shorter than python 2.3's heapq module, which is aimed at queuing rather than sifting. OTOH, it is unlikely to have any advantage over 2.4's heapq, which (I hear) has expanded functionality and is implemented in C.</p>
